dd918da8de ReplaceMesh Actuator option to replace the physics mesh and display mesh + python api options.
When the mesh field is left blank and Physics option is enabled, it reinstances the physics mesh from the existing mesh.
like calling gameOb.reinstancePhysicsMesh() from python.

e9ca43521f BGE Physics
Add support back for reinstancePhysics mesh, a frequently requested feature in the BGE forums.
from what I can tell Sumo supported this but bullet never did.
Currently only accessible via python at the moment.

- rigid body, dynamic, static types work.
- instanced physics meshes are modified too.
- compound shapes are not supported.

Physics mesh can be re-instanced from...
* shape keys & armature deformations
* subsurf (any other modifiers too)
* RAS_TexVert's (can be modified from python)

Moved the reinstancePhysicsMesh functions from RAS_MeshObject into KX_GameObject since the physics data is stored here.

9a7ea9664e BGE PyAPI support for subclassing any BGE game type from python, scripters define extra functions on gameObjects.
Adding a UI to set the type on startup can be added easily.

# ----
class myPlayer(GameTypes.KX_GameObject):
  def die(self):
    # ... do stuff ...
    self.endObject()

# make an instance
player = myPlayer(gameOb) # gameOb is made invalid now.
player.die()

# ----

One limitation (which could also be an advantage), is making the subclass instance will return that subclass everywhere, you cant have 2 different subclasses of the same BGE data at once.

6b9f3b5f5c BGE Python API
Remove the last of the odd C++/python wrapper code from http://www.python.org/doc/PyCPP.html (~1998)

* Use python subclasses rather then having fake subclassing through get/set attributes calling parent types.
* PyObject getset arrays are created while initializing the types, converted from our own attribute arrays. This way python deals with subclasses and we dont have to define getattro or setattro functions for each type.
* GameObjects and Scenes no longer have attribute access to properties. only dictionary style access - ob['prop']
* remove each class's get/set/dir functions.
* remove isA() methods, can use PyObject_TypeCheck() in C and issubclass() in python.
* remove Parents[] array for each C++ class, was only used for isA() and wasnt correct in quite a few cases.
* remove PyTypeObject that was being passed as the last argument to each class (the parent classes too).

TODO -
* Light and VertexProxy need to be converted to using attributes.
* memory for getset arrays is never freed, not that bad since its will only allocates once.

Note that the animation conversion from existing 2.4x blend files doesnt yet set the Action pointer in the actuator so the only way to test is to use the python api to set the new converted action active on the actuator because there is no user interface.

2faf20c4b3 BGE Action Actuator setChannel() function was broken in a number of ways.
* extract_pose_from_pose only checked one of the list items for NULL when looping over them yet its possible they are different sizes.
* game_free_pose needed to be used rather then MEM_freeN, channels would never be freed leaking memory.
* setChannel() would make a new pose that wasnt aligned with the existing pose, the lists are assumed aligned so when extracting the channels its unlikely this was ever useful.
* Added getChannel() - returns pose loc/size/quat
* Added option args for setChannel(channel, matrix) or setChannel(channel, loc, size, quat)

eb8c5f3272 Set default constraint solver mode more compatible to Blender 2.48 settings, this fixes rigid body stacking in this blend file:
http://blenderartists.org/forum/showpost.php?p=1382653&postcount=102

(todo: expose this setting in World setting GUI)

Expose contact processing threshold in Advanced GUI, next to rigid body margin, called CPT.
Default to 1, makes rigid body stacking a bit more stable, smaller values makes sliding easier (at the cost of easier jittering).
Disabled for 'dynamic' objects that don't rotate, because characters etc. always need smooth sliding.

5441323dca BGE: fix memleaks.
SCA_RandomActuator: The random generator was shared between replicas and not deleted. Added ref counting between replicas to allow deletion at the end.
KX_Camera: The scenegraph node was not deleted for temporary cameras (ImageMirror and shadow), causing 500 bytes leak per frame and per shadow light.
KX_GameActuator: Global dictionary buffer was not deleted after saving.
KX_MotionState: The motion state for compound child was not deleted
KX_ReplaceMeshActuator: The mesh was unnecessarily converted for each actuator and not deleted, causing large memleak.

After these fix, YoFrankie runs without memleak.

036ebc5523 BGE: GUI control over frame rate, logic rate, physics rate and physics subrate.
Four new buttons in World settings to control frame rate:
fps:  Nominal frame rate in frame per second.
      Also sets the physics timestep = 1/fps
phys: Maximum number of physics timestep per game frame in case
      the actual fps is less than nominal. This allows the 
      physics to keep up with real time even if the graphics slows
      down the game.
sub:  Fixed number of simulation substeps per physic timestep.
      Improves the precision of the physics simulation. Useful for
      fast moving objects for example.
log:  Maximum number of logic steps per game frame in case the 
      actual fps is less than nominal. This allows the logic
      system to follow the physics simulation. 
      Upper bound = phys 
      (setting the value higher than phys has no effect).
      On games with heavy logic system, it is useful to set this
      value to 1, to keep logic time under control.

All these values were already accessible from Python except phys:

GameLogic.getMaxPhysicsFrame():
	Gets the maximum number of physics frame per render frame.

GameLogic.setMaxPhysicsFrame(phys):
	Sets the maximum number of physics timestep that are executed per render frame.
	Higher value allows physics to keep up with realtime even if graphics slows down the game.
	Physics timestep is fixed and equal to 1/tickrate (see setLogicTicRate)
	maxphysics/ticrate is the maximum delay of the renderer that physics can compensate.
      phys: integer

06a7155b68 BGE: user control to compound shape and setParent.
Compound shape control
======================
1) GUI control
It is now possible to control which child shape is added to 
a parent compound shape in the Physics buttons. The "Compound"
shape button becomes "Add to parent" on child objects and
determines whether the child shape is to be added to the top
parent compound shape when the game is stated.

Notes: * "Compound" is only available to top parent objects
         (objects without parent).
       * Nesting of compound shape is not possible: a child
         object with "Add to parent" button set will be added
         to the top parent compound shape, regardless of its
         position in the parent-child hierarchy and even if its
         immediate parent doesn't have the "Add to parent" button set.

2) runtime control
It is now possible to control the compound shape at runtime:
The SetParent actuator has a new "Compound" button that indicates
whether the object shape should be added to the compound shape
of the parent object, provided the parent has a compound shape
of course. If not, the object retain it's individual state
while parented.
Similarly, the KX_GameObject.setParent() python function has
a new compound parameter.

Notes: * When an object is dynamically added to a compound 
         shape, it looses temporarily all its physics capability
         to the benefit of the parent: it cannot register collisions
         and the characteristics of its shape are lost (ghost, sensor,
         dynamic, etc.). 
       * Nested compound shape is not supported: if the object
         being parented is already a compound shape, it is not
         added to the compound parent (as if the Compound option 
         was not set in the actuator or the setParent function).
       * To ensure compatibility with old blend files, the Blender
         subversion is changed to 2.48.5 and the old blend files
         are automatically converted to match the old behavior: 
         all children of a Compound object will have the "Add to
         parent" button set automatically.

Child ghost control
===================
It is now possible to control if an object should becomes ghost
or solid when parented. This is only applicable if the object
is not added to the parent compound shape (see above).
A new "Ghost" button is available on the SetParent actuator to 
that effect. Similarly the KX_GameObject.setParent() python function
has a new compound parameter.

Notes: * This option is not applicable to sensor objects: they stay
         ghost all the time.
       * Make sure the child object does not enter in collision with
         the parent shape when the Ghost option if off and the parent is
         dynamic: the collision creates a reaction force but the parent
         cannot escape the child, so the force builds up and produces
         eratic movements.
       * The collision capability of an ordinary object (dynamic or static)
         is limited when it is parented: it becomes automatically static
         and can only detect dynamic and sensor objects.
       * A sensor object retain its full collision capability when parented:
         it can detect static and dynamic object.

Python control
==============
KX_GameObject.setParent(parent,compound,ghost):
	Sets this object's parent. 
	Control the shape status with the optional compound and ghost parameters:
	compound=1: the object shape should be added to the parent compound shape (default)
	compound=0: the object should keep its individual shape. 
	In that case you can control if it should be ghost or not:
	ghost=1 if the object should be made ghost while parented (default)
	ghost=0 if the object should be solid while parented 
	Note: if the object type is sensor, it stays ghost regardless of ghost parameter
		
	parent: KX_GameObject reference or string (object name w/o OB prefix)

2ac81cc7ad BGE soft body: give access to the soft body collision margin in the Advanced panel. By default the collision margin is set to 0.25, which causes the soft body to somewhat float above the ground. You can decrease this value to get more realistic collision.

07fc2aa526 BGE #18665: Servo control and relative motion
Servo control motion actuator did not work as expected when the object
is moving on a moving platform. 

This patch introduces a new Ref field in the servo motion actuator
to set a reference object for the velocity calculation.
You can set the object during the game using the actuator "reference"
attribute; use an object name or an object reference.

The servo controller takes into account the angular velocity of the
reference object to compute the relative local velocity.

9a40f4d2a6 BGE: bookmark option on controller to make them run before all other controllers.
A new bookmark button is available on the controller UI. 
When set, the controller is guaranteed to execute before all
other non-bookmarked controllers, provided it is scheduled 
for execution. 

This is useful for initialization scripts that run once at startup or
scripts that must set some prerequisite for the other controllers at
the start of each logic frame.

This feature is also available at python level with the "bookmark"
attribute. It can be changed during the game.

Note that if several script are bookmarked, their relative order of 
execution is not guaranteed. Make sure they don't depend on each other.

3ea1c1b4b6 BGE: new sensor object to generalize Near and Radar sensor, static-static collision capbility.
A new type of "Sensor" physics object is available in the GE for advanced
collision management. It's called Sensor for its similarities with the
physics objects that underlie the Near and Radar sensors.
Like the Near and Radar object it is:
- static and ghost
- invisible by default
- always active to ensure correct collision detection
- capable of detecting both static and dynamic objects
- ignoring collision with their parent
- capable of broadphase filtering based on:
  * Actor option: the collisioning object must have the Actor flag set to be detected
  * property/material: as specified in the collision sensors attached to it
  Broadphase filtering is important for performance reason: the collision points
  will be computed only for the objects that pass the broahphase filter.
- automatically removed from the simulation when no collision sensor is active on it

Unlike the Near and Radar object it can:
- take any shape, including triangle mesh
- be made visible for debugging (just use the Visible actuator)
- have multiple collision sensors using it

Other than that, the sensor objects are ordinary objects. You can move them
freely or parent them. When parented to a dynamic object, they can provide
advanced collision control to this object.

The type of collision capability depends on the shape:
- box, sphere, cylinder, cone, convex hull provide volume detection.
- triangle mesh provides surface detection but you can give some volume
  to the suface by increasing the margin in the Advanced Settings panel.
  The margin applies on both sides of the surface.

Performance tip:
- Sensor objects perform better than Near and Radar: they do less synchronizations
  because of the Scenegraph optimizations and they can have multiple collision sensors
  on them (with different property filtering for example).
- Always prefer simple shape (box, sphere) to complex shape whenever possible.
- Always use broadphase filtering (avoid collision sensor with empty propery/material)
- Use collision sensor only when you need them. When no collision sensor is active
  on the sensor object, it is removed from the simulation and consume no CPU.

Known limitations:
- When running Blender in debug mode, you will see one warning line of the console:
  "warning btCollisionDispatcher::needsCollision: static-static collision!"
  In release mode this message is not printed.
- Collision margin has no effect on sphere, cone and cylinder shape.

Other performance improvements:
- Remove unnecessary interpolation for Near and Radar objects and by extension
  sensor objects.
- Use direct matrix copy instead of quaternion to synchronize orientation.

Other bug fix:
- Fix Near/Radar position error on newly activated objects. This was causing
  several detection problems in YoFrankie
- Fix margin not passed correctly to gImpact shape.
- Disable force/velocity actions on static objects

d95a109990 BGE modifier: generate correct physic shape, share static derived mesh, share display list.
This commit completes the support for modifiers in the BGE.
- The physic shape is generated according to the derived mesh. 
  This is true for all types of shapes and all types of 
  objects except soft body.
- Optimization for static derived mesh (mesh with modifiers
  but no armature and no shape keys). Replicas will share
  the derived mesh and the display list: less memory and
  faster rendering. With this optimization, the static 
  derived mesh will render as fast as if the modifiers were
  applied.

Known Limits:
- Sharing of mesh and display list is only possible between
  in-game replicas or dupligroup. If you want to instantiate
  multiple objects with modifiers, use dupligroup to ensure
  best memory and GPU utilization.
- rayCast() will interact with the derived mesh as follow:
  Hit position and hit normal are the real values according
  to the derived mesh but the KX_PolyProxy object refers to
  the original mesh. You should use it only to retrieve the
  material.
- Dynamic derived mesh have very poor performance:
  They use direct openGL calls for rendering (no support
  for display list and vertex array) and they dont't share
  the derived mesh memory. Always apply modifiers on dynamic
  mesh for best performance.
- Time dependent modifiers are not supported.
- Modifiers are not supported for Bullet soft body.

386122ada6 BGE performance, 4th round: logic
This commit extends the technique of dynamic linked list to the logic
system to eliminate as much as possible temporaries, map lookup or 
full scan. The logic engine is now free of memory allocation, which is
an important stability factor. 

The overhead of the logic system is reduced by a factor between 3 and 6
depending on the logic setup. This is the speed-up you can expect on 
a logic setup using simple bricks. Heavy bricks like python controllers
and ray sensors will still take about the same time to execute so the
speed up will be less important.

The core of the logic engine has been much reworked but the functionality
is still the same except for one thing: the priority system on the 
execution of controllers. The exact same remark applies to actuators but
I'll explain for controllers only:

Previously, it was possible, with the "executePriority" attribute to set
a controller to run before any other controllers in the game. Other than
that, the sequential execution of controllers, as defined in Blender was
guaranteed by default.

With the new system, the sequential execution of controllers is still 
guaranteed but only within the controllers of one object. the user can
no longer set a controller to run before any other controllers in the
game. The "executePriority" attribute controls the execution of controllers
within one object. The priority is a small number starting from 0 for the
first controller and incrementing for each controller.

If this missing feature is a must, a special method can be implemented
to set a controller to run before all other controllers.

Other improvements:
- Systematic use of reference in parameter passing to avoid unnecessary data copy
- Use pre increment in iterator instead of post increment to avoid temporary allocation
- Use const char* instead of STR_String whenever possible to avoid temporary allocation
- Fix reference counting bugs (memory leak)
- Fix a crash in certain cases of state switching and object deletion
- Minor speed up in property sensor
- Removal of objects during the game is a lot faster

be2c21bcdb BGE logic: new sensor "tap" option to generate automatically on/off pulses
When enabled, this option converts any positive trigger from the sensor
into a pair of positive+negative trigger, with the negative trigger sent
in the next frame. The negative trigger from the sensor are not passed
to the controller as the option automatically generates the negative triggers. 
From the controller point of view, the sensor is positive only for 1 frame, 
even if the underlying sensor state remains positive.

The option interacts with the other sensor option in this way:
- Level option: tap option is mutually exclusive with level option. Both
  cannot be enabled at the same time.
- Invert option: tap option operates on the negative trigger of the 
  sensor, which are converted to positive trigger by the invert option.
  Hence, the controller will see the sensor positive for 1 frame when 
  the underlying sensor state turns negative. 
- Positive pulse option: tap option adds a negative trigger after each
  repeated positive pulse, unless the frequency option is 0, in which case
  positive pulse are generated on every frame as before, as long as the
  underlying sensor state is positive.
- Negative pulse option: this option is not compatible with tap option
  and is ignored when tap option is enabled.

Notes:
- Keyboard "All keys" is handled specially when tap option is set:
  There will be one pair of positive/negative trigger for each new 
  key press, regardless on how many keys are already pressed and there
  is no trigger when keys are released, regardless if keys are still
  pressed. 
  In case two keys are pressed in succesive frames, there will
  be 2 positive triggers and 1 negative trigger in the following frame.

3abb8e8e68 BGE performance: second round of scenegraph improvement.
Use dynamic linked list to handle scenegraph rather than dumb scan
of the whole tree. The performance improvement depends on the fraction
of moving objects. If most objects are static, the speed up is 
considerable. The following table compares the time spent on 
scenegraph before and after this commit on a scene with 10000 objects
in various configuratons:

Scenegraph time (ms)              Before         After
(includes culling)

All objects static,               8.8            1.7  
all visible but small fraction          
in the view frustrum

All objects static,               7,5            0.01
all invisible.

All objects moving,               14.1           8.4
all visible but small fraction
in the view frustrum

This tables shows that static and invisible objects take no CPU at all
for scenegraph and culling. In the general case, this commit will 
speed up the scenegraph between 2x and 5x. Compared to 2.48a, it should
be between 4x and 10x faster. Further speed up is possible by making
the scenegraph cache-friendly.

Next round of performance improvement will be on the rasterizer: use
the same dynamic linked list technique for the mesh slots.

Option to run a function in a module rather then a script from a python controller, this has a number of advantages.

- No allocating and freeing the namespace dictionary for every time its triggered
  (hard to measure the overhead here, but in a test with calling 42240 scripts a second each defining 200 vars, using modules was ~25% faster)

- Ability to use external python scripts for game logic.

- Convenient debug option that lets you edit scripts while the game engine runs.

PyObjectPlus::ProcessReplica() is now called when any of its subclasses are replicated.

This is important because PyObjectPlus::ProcessReplica() NULL's the 'm_proxy' python pointer I added recently.
Without this a replicated subclass of PyObjectPlus could have an invalid pointer (crashing the BGE).

This change also means CValue::AddDataToReplica() can be moved into CValue::ProcessReplica() since ProcessReplica is always called.

d11a5bbef2 BGE: Support mesh modifiers in the game engine.
Realtime modifiers applied on mesh objects will be supported in 
the game engine with the following limitations:

- Only real time modifiers are supported (basically all of them!)
- Virtual modifiers resulting from parenting are not supported: 
  armature, curve, lattice. You can still use these modifiers 
  (armature is really not recommended) but in non parent mode. 
  The BGE has it's own parenting capability for armature.
- Modifiers are computed on the host (using blender modifier
  stack).
- Modifiers are statically evaluated: any possible time dependency
  in the modifiers is not supported (don't know enough about
  modifiers to be more specific).
- Modifiers are reevaluated if the underlying mesh is deformed
  due to shape action or armature action. Beware that this is 
  very CPU intensive; modifiers should really be used for static
  objects only.
- Physics is still based on the original mesh: if you have a 
  mirror modifier, the physic shape will be limited to one half
  of the resulting object. Therefore, the modifiers should 
  preferably be used on graphic objects.
- Scripts have no access to the modified mesh. 
- Modifiers that are based on objects interaction (boolean,..)
  will not be dependent on the objects position in the GE.
  What you see in the 3D view is what you get in the GE regardless
  on the object position, velocity, etc.

Besides that, the feature is compatible with all the BGE features
that affect meshes: armature action, shape action, relace mesh, 
VideoTexture, add object, dupligroup.

Known problems:
- This feature is a bit hacky: the BGE uses the derived mesh draw 
  functions to display the object. This drawing method is a
  bit slow and is not 100% compatible with the BGE. There may
  be some problems in multi-texture mode: the multi-texture
  coordinates are not sent to the GPU. 
  Texface and GLSL on the other hand should be fully supported.
- Culling is still based on the extend of the original mesh. 
  If you have a modifer that extends the size of the mesh, 
  the object may disappear while still in the view frustrum.
- Derived mesh is not shared between replicas.
  The derived mesh is allocated and computed for each object
  with modifiers, regardless if they are static replicas.
- Display list are not created on objects with modifiers.
  
I should be able to fix the above problems before release.
However, the feature is already useful for game development.
Once you are ready to release the game, you can apply the modifiers
to get back display list support and mesh sharing capability.

MSVC, scons, Cmake, makefile updated.

8d2cb5bea4 BGE Python API
This changes how the BGE classes and Python work together, which hasnt changed since blender went opensource.
The main difference is PyObjectPlus - the base class for most game engine classes, no longer inherit from PyObject, and cannot be cast to a PyObject.

This has the advantage that the BGE does not have to keep 2 reference counts valid for C++ and Python.

Previously C++ classes would never be freed while python held a reference, however this reference could be problematic eg: a GameObject that isnt in a scene anymore should not be used by python, doing so could even crash blender in some cases.

Instead PyObjectPlus has a member "PyObject *m_proxy" which is lazily initialized when python needs it. m_proxy reference counts are managed by python, though it should never be freed while the C++ class exists since it holds a reference to avoid making and freeing it all the time.
When the C++ class is free'd it sets the m_proxy reference to NULL, If python accesses this variable it will raise a RuntimeError, (check the isValid attribute to see if its valid without raising an error).
- This replaces the m_zombie bool and IsZombie() tests added recently.

In python return values that used to be..
 return value->AddRef();
Are now
 return value->GetProxy();
or...
 return value->NewProxy(true); // true means python owns this C++ value which will be deleted when the PyObject is freed

51b4145841 BGE Scenegraph and View frustrum culling improvement.
This commit contains a number of performance improvements for the
BGE in the Scenegraph (parent relation between objects in the
scene) and view frustrum culling.

The scenegraph improvement consists in avoiding position update
if the object has not moved since last update and the removal
of redundant updates and synchronization with the physics engine.

The view frustrum culling improvement consists in using the DBVT
broadphase facility of Bullet to build a tree of graphical objects
in the scene. The elements of the tree are Aabb boxes (Aligned 
Axis Bounding Boxes) enclosing the objects. This provides good
precision in closed and opened scenes. This new culling system
is enabled by default but just in case, it can be disabled with
a button in the World settings. There is no do_version in this
commit but it will be added before the 2.49 release. For now you
must manually enable the DBVT culling option in World settings
when you open an old file.

The above improvements speed up scenegraph and culling up to 5x.
However, this performance improvement is only visible when
you have hundreds or thousands of objects.

The main interest of the DBVT tree is to allow easy occlusion
culling and automatic LOD system. This will be the object of further
improvements.

fd2b115678 Python BGE API
- Initialize python types with PyType_Ready, which adds methods to the type dictionary.
- use Pythons get/setattro (uses a python string for the attribute rather then char*). Using basic C strings seems nice but internally python converts them to python strings and discards them for most functions that accept char arrays.
- Method lookups use the PyTypes dictionary (should be faster then Py_FindMethod)
- Renamed __getattr -> py_base_getattro, _getattr -> py_getattro, __repr -> py_base_repr, py_delattro, py_getattro_self etc.

From here is possible to put all the parent classes methods into each python types dictionary to avoid nested lookups (api has 4 levels of lookups in some places), tested this but its not ready yet.

Simple tests for getting a method within a loop show this to be between 0.5 and 3.2x faster then using Py_FindMethod()

a4ad52f1aa New Pulse option for the collision sensor (off by default wont change existing logic)
Previously only the first collision would trigger an event (no collisions a negative event ofcourse)

With the Pulse option enabled, any change to the set of colliding objects will trigger an event.

Added this because there was no way to count how many sheep were on a platform in YoFrankie without running a script periodically.

Changes in collision are detected by comparing the number of objects colliding with the last event, as well as a hash made from the object pointers.

Also changed the touch sensors internal list of colliding objects to only contain objects that match the property or material.

- pulse isnt a great name, could change this.

c77af31166 Minor speedups for the BGE
* Where possible use vec.setValue(x,y,z) to assign values to a vector instead of vec= MT_Vector3(x,y,z), for MT_Point and MT_Matrix types too.
* Comparing TexVerts was creating 10 MT_Vector types - instead compare as floats.
* Added SG_Spatial::SetWorldFromLocalTransform() since the local transform is use for world transform in some cases.
* removed some unneeded vars from UpdateChildCoordinates functions 
* Py API - Mouse, Ray, Radar sensors - use PyObjectFrom(vec) rather then filling the lists in each function. Use METH_NOARGS for get*() functions.

- Fix: modal keymaps for editmode in view3d were not set again
  when you copy areas or go fullscreen.

- Improved "redo last op" (F6) to search back in history for
  a redoable operator. Operator also used wrong pupmenu type.

- On creating new FCurve editor, the channel rainbow colors are
  set correct.

- EditMesh: fixed code for Spin/Screw, correct props, init and
  error reporting. (Spin hotkey ALT+R temporary)

- recompiled all to check for uninitialized variable warnings.

View3D has been split now in a local part (RegionView3D) and a
per-area part (old View3D). Currently local is:

- view transform
- camera zoom/offset
- gpencil (todo)
- custom clipping planes

Rest is in Area still, like active camera, draw type, layers,
localview, custom centers, around-settings, transform widget,
gridlines, and so on (mostly stuff as available in header).

To see it work; also added new feature for region split, 
press SHIFT+ALT+CTRL+S for four-split. 
The idea is to make a preset 4-split, configured to stick
to top/right/front views for three views.
Another cool idea to explore is to then box-clip all drawing
based on these 3 views.

Note about the code:
- currently view3d still stores some depricated settings, to
  convert from older files. Not all settings are copied over
  though, like custom clip planes or the 'lock view to object'.
- since some view3d ops are now on area level, the operators
  for it should keep track of that.

Bugfix in transform: quat initialize in operator-invoke missed
one zero.

Als brought back GE to compile for missing Ipos and channels.

The old favorite G.scene gone! Man... that took almost 2 days.
Also removed G.curscreen and G.edbo.

Not everything could get solved; here's some notes.
- modifiers now store current scene in ModifierData. This is not
  meant for permanent, but it can probably stick there until we
  cleaned the anim system and depsgraph to cope better with
  timing issues.
- Game engine G.scene should become an argument for staring it.
  Didn't solve this yet.
- Texture nodes should get scene cfra, but the current implementation
  is too tightly wrapped to do it easily.

bdfe7d89e2 Merge of trunk into blender 2.5:
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r12987:17416

Issues:
* GHOST/X11 had conflicting changes. Some code was added in 2.5, which was
  later added in trunk also, but reverted partially, specifically revision
  16683. I have left out this reversion in the 2.5 branch since I think it is
  needed there.
  http://projects.blender.org/plugins/scmsvn/viewcvs.php?view=rev&root=bf-blender&revision=16683
* Scons had various conflicting changes, I decided to go with trunk version
  for everything except priorities and some library renaming.
* In creator.c, there were various fixes and fixes for fixes related to the -w
  -W and -p options. In 2.5 -w and -W is not coded yet, and -p is done
  differently. Since this is changed so much, and I don't think those fixes
  would be needed in 2.5, I've left them out.
* Also in creator.c: there was code for a python bugfix where the screen was not
  initialized when running with -P. The code that initializes the screen there
  I had to disable, that can't work in 2.5 anymore but left it commented as a
  reminder.

Further I had to disable some new function calls. using src/ and python/, as
was done already in this branch, disabled function calls:
* bpath.c: error reporting
* BME_conversions.c: editmesh conversion functions.
* SHD_dynamic: disabled almost completely, there is no python/.
* KX_PythonInit.cpp and Ketsji/ build files: Mathutils is not there, disabled.
* text.c: clipboard copy call.
* object.c: OB_SUPPORT_MATERIAL.
* DerivedMesh.c and subsurf_ccg, stipple_quarttone.

Still to be done:
* Go over files and functions that were moved to a different location but could
  still use changes that were done in trunk.

8550c2b594 BGE patch: new force field constraint actuator
A new type of constraint actuator is available: Force field.
It provides a very similar service to the Fh material feature
but with some specificities:
- It is defined at the object level: each object can have 
  different settings and you don't need to use material.
- It can be applied in all 6 directions and not just -Z.
- It can be enabled/disabled easily (it's an actuator).
- You can have multiple force fields active at the same time
  on the same object in different direction (think of a 
  space ship in a tunnel with a repulsive force field
  on each wall).
- You can have a different damping for the rotation.

Besides that it provides the same dynamic behavior and the 
parameters are self explanatory.
It works by adapting the linear and angular velocity: the
dynamic is independent of the mass. It is compatible with
all other motion actuators.

Note: linear and anysotropic friction is not yet implemented,
the only friction will come from the object damping parameters. 
Support for friction will be added in a future revision.

41a0b56b70 BGE patch: new Physics button and margin parameter in Logic panel. Change subversion.
The Physics button controls the creation of a physics representation 
of the object when starting the game. If the button is not selected,
the object is a pure graphical object with no physics representation
and all the other physics buttons are hidden.
Selecting this button gives access to the usual physics buttons.
The physics button is enabled by default to match previous Blender
behavior.

The margin parameter allows to control the collision margin from
the UI. Previously, this parameter was only accessible through 
Python. By default, the collision margin is set to 0.0 on static 
objects and 0.06 on dynamic objects. 
To maintain compatibility with older games, the collision margin
is set to 0.06 on all objects when loading older blend file.

Note about the collision algorithms in Bullet 2.71
--------------------------------------------------
Bullet 2.71 handles the collision margin differently than Bullet 2.53
(the previous Bullet version in Blender). The collision margin is 
now kept "inside" the object for box, sphere and cylinder bound 
shapes. This means that two objects bound to any of these shape will
come in close contact when colliding. 
The static mesh, convex hull and cone shapes still have their
collision margin "outside" the object, which leaves a space of 1
or 2 times the collision margin between objects. 

The situation with Bullet 2.53 was more complicated, generally
leading to more space between objects, except for box-box collisions. 

This means that running a old game under Bullet 2.71 may cause
visual problems, especially if the objects are small. You can fix
these problems by changing some visual aspect of the objects: 
center, shape, size, position of children, etc.
