This one deals with the very small default clipend value ( 100.0 ) when pressing P to run the GE from a non-camera view. ( ie if the user zooms out a bit from the default box area, the box will get clipped out of view, so it's a WFT from the user )
To see what this fixes, load up Blender default scene, go into perspective, and press P. Everything looks grand. Now, zoom out until the box is about 10 pixels high, and press P again. The box will disappear / be clipped out.
I've set the clip end to the maximum ( 5000 ) as defined in Camera.h.
This should be suitable for inclusion in 2.47 branch also.
=======================================
Alpha blending + sorting was revised, to fix bugs and get it
to work more predictable.
* A new per texture face "Sort" setting defines if the face
is alpha sorted or not, instead of abusing the "ZTransp"
setting as it did before.
* Existing files are converted to hopefully match the old
behavior as much as possible with a version patch.
* On new meshes the Sort flag is disabled by the default, to
avoid unexpected and hard to find slowdowns.
* Alpha sorting for faces was incredibly slow. Sorting faces
in a mesh with 600 faces lowered the framerate from 200 to
70 fps in my test.. the sorting there case goes about 15x
faster now, but it is still advised to use Clip Alpha if
possible instead of regular Alpha.
* There still various limitations in the alpha sorting code,
I've added some comments to the code about this.
Some docs at the bottom of the page:
http://www.blender.org/development/current-projects/changes-since-246/realtime-glsl-materials/
Merged some fixes from the apricot branch, most important
change is that tangents are now exactly the same as the rest
of Blender, instead of being computed in the game engine with a
different algorithm.
Also, the subversion was bumped to 1.
Bone-locking should only be set if the bone (and not its parent/children) are selected. Transposition error from the patch (I had to manually apply as there were some oddities about the patch file).
The pasting code for text-buttons (when hovering over the button), was incorrectly using the drawstr (i.e. the string that is displayed in the text-button, and includes the 'name' of the button) as the old value. This meant that the renaming code could not correctly detect matches to rename.
This bug-report revealed a critical error made in the menus for Constraints Owner/Target spaces. It seems that the wrong values have been used for 'pose space' and 'local with parent' space. This has now been rectified, so that old rigs won't break (just that the labels will be a bit different).

This patch adds the ability to lock transformation on bones in edit mode, to protect them from accidental editing.
Bones can be locked from the editing buttons, the transform property panel, the specials popup menu or the python api.
This now works even when there is a proxy-protected bone selected with a few differences.
* The Transform Locks, IK-Flags, and Custom Bone Shape settings are unavailable, as they would be reset by the proxy protection anyway
Also, the Copy Constraints options have been altered so that they do NOT free all existing constraints on the target bones before copying.
* Constraints are now appended to the end of the constraint stacks, with those added to bones belonging on proxy protected layers getting tagged as 'local' constraints.
* This is more useful for riggers than the previous behaviour (which was quite nasty too).
Render/postrender events were missing from bg rendering (and also from rendering called inside scripts). Found this because of bug #17389, the code to prevent race conditions with pynodes is currently inside BPY_do_all_scripts (that runs scriptlinks) and so was not being called in bg mode or rendering via scripts.

This commit attempts to fix some of the problems with the accuracy of strokes recorded.
I've disabled the post-draw smoothing of strokes as it deviated from the source stroke too much. This was introduced to try to eliminate the effects of fine 'jitter' (which is especially noticable when using optical mice + fast computer).
Now, I've introduced two thresholds which determine the 'minimum' distances that the mouse needs to have moved from the previous mouse-coordinates recorded, to be recorded. These are currently hardcoded, but may be exposed in the UI if there is significant need to do so.
- The first is for the distance that the mouse must have moved on both axes to be considered.
- The second is for the 'pythagorean' distance that needs to have been travelled by the mouse.
* For constraint mesh-targets, the check for whether the target mesh was in EditMode didn't check to see if the target mesh was the mesh in EditMode.
Thanks jaguarandi for catching that!
* Bumped up size of buffer for grease-pencil drawing after seeing a program written in 1989 that had a 100 times larger buffer
Early Ehlinger reported a deadlock when a script tells Blender to render an animation and there are pynodes. While investigating I saw related crashes in bg (blender -b) mode, still not fixed. This commit tries to fix the problem for interactive mode, then. What it does is releasing the lock before rendering and relocking after that, like theeth suggests in the bug report:
http://projects.blender.org/tracker/?func=detail&atid=125&aid=17389&group_id=9
It turns out the material AmbCol property was never working properly, or even supported in the renderer, so I've removed it. Also included is a fix to make the 'Amb' input work properly too.
left overs from new particles
-wind and force did not work if aero or edge collision was activated.
-force field had flipped sign compared to particles
tsk who thinks a attractive force should negative sign? well... i am passionless with that.
-adapted effect of wind and fields on softbodies such that softbody "particles" and particle "particles" behave consistently
note!
effect of wind is 1/25 compared to before
other forces 1/10
New Stuff:
* Alt-XKEY / Alt-DelKey will now activate the Grease Pencil "Erase" menu. This will only show up when it's relevant (i.e. when there exists Grease Pencil data). It should make it faster to quickly delete the last stroke made. This hotkey has been added to the tooltips of the relevant buttons.
* Finished off colouring of 'active' layers panel so that they are now easily identify-able. This could also be done for Constraints, but the 'active' one isn't that important there.
Bugfixes:
* Fixed bug with drawing gp-data sources in the Action Editor, which resulted in missing icons.
* Fixed buttons in Grease Pencil panel. My hasty attempt last night at making the Action Editor to refresh was causing problems.
* Added a (hopefully temporary) button that will be used to prevent drawing from occurring with Shift-LMB. This is useful when trying to select stuff sometimes, with LMB as select-button, especially when selecting a bunch of closely spaced bones might be interpreted as a new stroke.
Based on user feedback, I've made some changes to the Grease Pencil UI (most notably in 'Time Editing' facilities).
* 'Edit Timing' button gone
* Pin button and '<Grease Pencil Data' string gone from Action Editor
* Action Editor in 'Grease Pencil' mode now displays all grease-pencil datablocks for current screen.
* AE: GP-Datablocks are drawn like 'groups', with an expand/collapse button to show/hide layers. Its name shows the type of space it comes from, and shows indicative status info (i.e. for 3d-view, it shows view-angle)
* Added refresh calls for action editor after editing relevant data.
I haven't tested all tools yet, but most should be stable.
Also, I've removed some unnecessary buttons, and added a few tooltips. There's also some experimental code to try to get clearer indication of 'active' layer.
Fixes: [#17315] Sequencer: after undo there's no active object
closes: [#17357] fix for bug #17315 - Sequencer: after undo there's no active object
(kiemdoder: thanks for the patch, had to do it in a little bit different way,
since sort_seq will kill your sort order idea...)
The min/max parameters define a minimum/maximum angle
that the object axis can have with the reference
direction without being constrainted. The angle is
expressed in degree and is limited to 0-180 range.
The min/max parameters define a conical free zone
around the reference direction.
If the object axis is outside that free zone, the
actuator will tend to put it back using as a temporary
reference direction the vector that is exactly at
min or max degree of the reference direction
(depending if the axis angle is below the minimum
or above the maximum) and is located in the plane
formed by the axis and the reference direction.
With a low damping value, this is equivalent to
clamping the axis orientation within min/max degree
of the reference direction.
Backward compatibility corresponds to the absence
of free zone: min = max = 0.
Grease Pencil is a tool which allows you to draw freehand in some views, allowing you to annotate/scribble over the contents of that view in either 2d or 3d. This facilitates many easier communication and planning abilities.
To use, simply enable it from the View menu (choose 'Grease Pencil...' and click 'Use Grease Pencil'). Then, click+drag using the left-mouse button and the shift-key held to draw a stroke.

Particle patch from Cédric Paille: bugfixes and child-particles export improvements for .getLoc(), part.getRot() part.getSize(), part.getAge() methods.
Also fix a bug with part.randemission getter (was using PART_BOIDS_2D instead of PART_TRAND), plus typos and duplications in API documentation.
First batch of optimizaton of the bullet adaptation layer in the BGE.
- remove circular motion state update.
- optimization of physic adaptation layer for bullet: bypass
unecessary conversion of rotation matrix to quaternion and back.
- remove double updates during object replication.
Curve modifier on lattice suffered drawing updates, only when the system
was not animated though, missed depsgraph calls then.
Solved it by forcing lattice to always return displist for its vertices,
that's same as for how mesh/curve works now.
Specular render in Blender still had terminator problems... only the diffuse
part got "phong correction" applied. I didn't fix this before to not change
rendering results just before the release. Now there's time I hope?
Render results should only differ minimal, and only visible for low spec
hardness values (like 1 or 2)
Certain actuators hold a pointer to an objects: Property,
SceneCamera, AddObject, Camera, Parent, TractTo. When a
group is duplicated, the actuators that point to objects
within the group will be relinked to point to the
replicated objects and not to the original objects.
This helps to setup self-contained group with a camera
following a character for example.
This feature also works when adding a single object
(and all its children) with the AddObject actuator.
The second part of the patch extends the protection
against object deletion to all the actuators of the above
list (previously, only the TrackTo, AddObject and
Property actuators were protected). In case the target
object of these actuators is deleted, the BGE won't
crash.
This situation corresponds to a group containing only a portion
of a parent hierarchy (the Apricot team needed that to avoid
logic duplication). The BGE will instantiate only the
children that are in the group so that it follows the 3D view
more closely.
As a result, the logic links to the objects in the portion of the
hierarchy that was not replicated will point to inactive objects
(if the groups are stored in inactive layers as they should be).
To keep the logic system consistent, these links are automatically
removed.
This last part of the patch is a general fix that could go in
2.47 but as this situation does not normally occurs in pre-2.47
games, it is not needed.
the aspect of a block could become negative and default when scaling icons.
this is caused by the using viewRedrawForce (transforming a mesh) and drawing icons in the image panel.
must look into why bwin_getsinglematrix can give a negative value, probably because the opengl state is set incorrect.
This is still not correct because the aspect will be wrong. but at least it wont crash.
Blender duplicates groups in the 3D view at the location of objects having the DUPLIGROUP option set. This feature is now supported in the BGE: the groups will be instantiated as in the 3D view when the scene is converted. This is useful to populate a scene with multiple enemies without having to actually duplicate the objects in the blend file.
Notes: * The BGE applies the same criteria to instantiate the group as Blender to display them: if you see the group in the 3D view, it will be instantiated in the BGE.
* Groups are instantiated as if the object having the DUPLIGROUP option (usually an empty) executed an AddObject actuator on the top objects of the group (objects without parent).
* As a result, only intra-group parent relationship is supported: the BGE will not instantiate objects that have parents outside the group.
* Intra-group logic bricks connections are preserved between the duplicated objects, even between the top objects of the group.
* For best result, the state engine of the objects in the group should be self-contained: logic bricks should only have intra-group connections. Use messages to communicate with state engines outside the group.
* Nested groups are supported: if one or more objects in the group have the DUPLIGROUP option set, the corresponding groups will be instantiated at the corresponding position and orientation.
* Nested groups are instantiated as separate groups, not as one big group.
* Linked groups are supported as well as groups containing objects from the active layers.
* There is a difference in the way Blender displays the groups in the 3D view and how BGE instantiates them: Blender does not take into account the parent relationship in the group and displays the objects as if they were all children of the object having the DUPLIGROUP option. That's correct for the top objects of the group but not for the children. Hence the orientation of the children objects may be different in the BGE.
* An AddGroup actuator will be added in a future release.
If you enable the Proxy and Custom Dir options and later disable
the Proxy (but not the Custom Dir options), Blender crash every
time that you try select the strip, because the proxy don't exist
anymore.
The solution: only draw the Custom Dir button if the Proxy
option is enable.
* samples that wernt loaded could crash blender - divide by zero errors from having 0 channels or bits.
* could also corrupt memory when selecting samples with long names. from the sample selector menu.
Small one: changed the string attribute in multilayer exr files to be:
"2.43 and newer"
To indicate that it's about compatibility of the exr file, not the version
Blender saved it in.
Ztransp OSA render did not include z values anymore in pass... this is
not good Z anyway (aliased), but at least it's back now.
Note: for composites using Z values: use FSA for superior results.
Patch submitted by Roelf De Kock (kiemdoder)
The parts of the patch affecting the timeline were have not been committed, as there was a better solution.
When searching failed to find any matches, the pointer to a matching pose was cleared. However, it wasn't reset upon clearing the invalid search-string, so a crash occurred.
When the NKEY is pressed in the Action Editor while hovering over the keyframes area, a floating properties panel can now be accessed. It shows relevant properties for the active channel, however this is currently only for Action Groups. Action Channel support will come later.
The key benefit of this panel is that it is now possible to edit the colour set used by a group. Also, there is a button for selecting all the channels in that group (which can also be done by simply Ctrl-Shift clicking on any group).
When using states, an action like kick or throw can often switch out before finishing playing the action, and there was no way to play from the start frame the second time round. (even setting the actions current frame through python doesn't work work)
=============================
* Clean up and optimizations in skinned/deformed mesh code.
* Compatibility fixes and clean up in the rasterizer.
* Changes related to GLSL shadow buffers which should have no
effect, to keep the code in sync with apricot.
When changing the active action in the NLA editor with NLA-override off, armatures now have their restpose applied before the new action is evaluated.
I've commented the code here to make it clearer what is going on.

Fixes bug [#7969] Mirroring Object Breaks Radiosity Calculations
- copied from the tracker.
The code in this patch detects whether an object has negative scale (test the OB_NEG_SCALE bit in Object.transflag)
and then compensate for the negative scale when the surface normals are calculated for a radiosity render.
CDDM_apply_vert_coords needs a CDDerivedMesh, but it was getting a
CCGDerivedMesh from the preceding Subsurf modifier. This fix just makes
a CDDerivedMesh copy of the supplied DerivedMesh rather than using it directly.
