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.

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.

svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD

Notes:
* Game and sequencer RNA, and sequencer header are now out of date
  a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
  not needed anymore.
  * Fix "duplicate strip" always increase the user count for ipo.
  * IPO pinning on sequencer strips was lost during Undo.

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

Separate getting a normal attribute and getting __dict__, was having to do too a check for __dict__ on each class (multiple times per getattro call from python) when its not used that often.

dee32d0b3f BGE Python API
- initialize pythons sys.argv in the blenderplayer
- ignore all arguments after a single " - " in the blenderplayer (like in blender), so args can be passed to the game.
- add a utility function PyOrientationTo() - to take a Py euler, quat or 3x3 matrix and convert into a C++ MT_Matrix3x3.
- add utility function ConvertPythonToMesh to get a RAS_MeshObject from a KX_MeshProxy or a name.
- Added error prefix arguments to ConvertPythonToGameObject, ConvertPythonToMesh and PyOrientationTo so the error messages can include what function they came from.
- deprecated brick.getOwner() for the "owner" attribute.

33170295c8 use long long rather then int for storing game logic properties.
There were also some problems with int to python conversion
- assigning a PyLong to a KX_GameObject from python would raise an error
- PyLong were coerced into floats when used with internal CValue arithmetic

Changes...
- PyLong is converted into CIntValue for coercing and assigning from python
- CValue's generic GetNumber() function returns a double rather then a float.
- Print an error when a PyType cant be coerced into a CValue

Tested with python, expressions and property sensor.

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()

cdec2b3d15 BGE Python API
Use 'const char *' rather then the C++ 'STR_String' type for the attribute identifier of python attributes.

Each attribute and method access from python was allocating and freeing the string.
A simple test with getting an attribute a loop shows this speeds up attribute lookups a bit over 2x.

becd467be8 BGE patch: KX_GameObject::rayCast() improvements to have X-Ray option, return true face normal and hit polygon information.
rayCast(to,from,dist,prop,face,xray,poly):

The face paremeter determines the orientation of the normal: 
  0 or omitted => hit normal is always oriented towards the ray origin (as if you casted the ray from outside)
  1 => hit normal is the real face normal (only for mesh object, otherwise face has no effect)
The ray has X-Ray capability if xray parameter is 1, otherwise the first object hit (other than self object) stops the ray.
The prop and xray parameters interact as follow:
    prop off, xray off: return closest hit or no hit if there is no object on the full extend of the ray.
    prop off, xray on : idem.
    prop on,  xray off: return closest hit if it matches prop, no hit otherwise.
    prop on,  xray on : return closest hit matching prop or no hit if there is no object matching prop on the full extend of the ray.
if poly is 0 or omitted, returns a 3-tuple with object reference, hit point and hit normal or (None,None,None) if no hit.
if poly is 1, returns a 4-tuple with in addition a KX_PolyProxy as 4th element.

The KX_PolyProxy object holds information on the polygon hit by the ray: the index of the vertex forming the poylgon, material, etc.

Attributes (read-only):
 matname: The name of polygon material, empty if no material.
 material: The material of the polygon
 texture: The texture name of the polygon.
 matid: The material index of the polygon, use this to retrieve vertex proxy from mesh proxy
 v1: vertex index of the first vertex of the polygon, use this to retrieve vertex proxy from mesh proxy
 v2: vertex index of the second vertex of the polygon, use this to retrieve vertex proxy from mesh proxy
 v3: vertex index of the third vertex of the polygon, use this to retrieve vertex proxy from mesh proxy
 v4: vertex index of the fourth vertex of the polygon, 0 if polygon has only 3 vertex
     use this to retrieve vertex proxy from mesh proxy
 visible: visible state of the polygon: 1=visible, 0=invisible
 collide: collide state of the polygon: 1=receives collision, 0=collision free.
Methods:
 getMaterialName(): Returns the polygon material name with MA prefix
 getMaterial(): Returns the polygon material
 getTextureName(): Returns the polygon texture name
 getMaterialIndex(): Returns the material bucket index of the polygon. 
 getNumVertex(): Returns the number of vertex of the polygon.
 isVisible(): Returns whether the polygon is visible or not
 isCollider(): Returns whether the polygon is receives collision or not
 getVertexIndex(vertex): Returns the mesh vertex index of a polygon vertex
 getMesh(): Returns a mesh proxy

New methods of KX_MeshProxy have been implemented to retrieve KX_PolyProxy objects:
 getNumPolygons(): Returns the number of polygon in the mesh.
 getPolygon(index): Gets the specified polygon from the mesh.

More details in PyDoc.
