- Re-arrange locks, so no actual memory allocation
(which is relatively slow) happens from inside
the lock. operation system will take care of locks
which might be needed there on it's own.
- Use spin lock instead of mutex, since it's just
list operations happens from inside lock, no need
in mutex here.
- Use atomic operations for memory in use and total
used blocks counters.
This makes guarded allocator almost the same speed
as non-guarded one in files from Tube project.
There're still MemHead/MemTail overhead which might
be bad for CPU cache utilization
This commit fixes two different issues, which were caused by
how weights are being calculated for relative shapekeys.
Weights for key block used to saved in KeyBlock DNA structure,
which lead to situations when different objects could start
writing to the same weights array if they're sharing the same
key datablock.
Solved this in a way so weights are never stored in KeyBlock
and being passed to shapekeys routines as an array of pointers.
This way weights are still computed run-time (meaning they're
calculated before shapekey evaluation and freed afterwards).
This required some changes to GameEngine as well, to make it
never cache weights in the key blocks.
Another aspect of this commit makes it so weight for a given
vertex group is only computed once. So if multiple key blocks
are using the same influence vertex group, they'll share the
same exact weights array. This gave around 1.7x speedup in
test chinchilla file which is close enough to if we've been
caching weights permanently in DNA (test machine is dual-code
4 threads laptop, speedup measured in depsgraph_mt branch,
trunk might be not so much high speedup).
Some further speed is optimization possible, but it could be
done later as well.
Thanks Brecht for idea of how the things might be solved in
really clear way.

Move static variables to context filling in by this fcuntion
and owned by a callee function. This ensures no conflicts
between threads happens because of static variables used in
this function.
Also moved modifier types and virtual modifiers data to a
function called from creator. This is needed to be sure all
the information is properly initialied to the time when
threads starts to use this data.

Any GLSL materials loaded after lights are LibLoaded will now use the lights in
heir shaders. This includes materials loaded from the same scene as the LibLoaded
lights. We could later add a new flag to LibLoad to recompile all existing shaders,
but this commit should offer a lot more flexibility as is.
This will make transitions from older versions of Blender easier since VSYNC_ON
will be the default. This could have been changed in a do_version, but the vsync
code has yet to see an official release, so I figured this would be a bit nicer.
Also, this makes VSYNC_ON the default for new scenes as well.
Now sounds that stopped playing but are still kept in the device can be differentiated from paused sounds with this state.
This should also fix the performance issues mentioned in [#36466] End of SequencerEntrys not set correctly.
Please test if sound pausing, resuming and stopping works fine in the BGE and sequencer, my tests all worked fine, but there might be a use case that needs some fixing.
Fix: to swap the drawing order for the warp mesh polygon
The code was drawing CW instead of CCW.
It would work in some cases where the drawing flags would allow for the
back faces to be visible.
More specifically the alternative fix were:
glDisable ( GL_CULL_FACE );
glFrontFace( GL_CW );
Bug originally reported in the small_planetarium mailing list.
This bug fix was a comissioned job by a group who prefer not to be
credited. Thanks regardless.
They were caused by not having a free_windowmanager_cb set and by not having registered SpaceTypes, which meant data allocated for thosse SpaceTypes could not be freed. These were solved by defining a free_windowmanager_cb for the player that just frees wmWindows, and by making sure we only allocate memory for registered SpaceTypes.
Implementing a GetBlenderImage for KX_BlenderMaterial so that modifiers draw correctly in multitexture mode. The preexisting limitation of 1 texture per material on objects with modifiers in multitexture mode still exists.
