There is no real elegant solution here, ideally a modifier shall never *modify*
a source DM, but that would imply much better ways to ensure required data
is available in that source DM, which we do not have currently.
So instead, let's use brute force solution for now and always create a local copy
of our source DM, that we can modify to our heart content!
The bug header is wrong, the file contains the high pitched sound, but the bug that existed was that animation rendering did not use the high quality resampler, while audio mixdown does.
Blender uses the low quality resampler to be as little CPU consuming as possible.
Otherwise user may have a hard time understanding why their modifier is no more working
after they e.g. deleted some vertices... including the root one. ;)
KX_IPOActuator is not used since 2.4.
This patch removes:
- KX_IPOActuator.h/cpp;
- Python doc;
- Write of IPO actuator in write.c;
- Allocation of IPOactuator in sca.c;
- Conversion in KX_ConvertActuators.cpp;
- Initialization of the python proxy in KX_PythonInitTypes.cpp;
- Other minor remove in logic_windows.c and in KX_PythonInit.cpp.

Crash was happening due to OpenGL free from the non-main thread. Ideally we need
to implement somewhat delayed unused buffer free for OpenSubdiv similar to what we
are doing in GPU module.
We needed the 'background' feature here, since we never wait on those preview-generation tasks.
Note that it also simplifies the code, and as usual testing is needed here on all possible platforms...
With current code, in single-threaded context, a pool of task may never be executed
until one calls BLI_task_pool_work_and_wait() on it, this is not acceptable for
asynchronous tasks where you never want to actually lock the main thread.
This commits adds an extra thread in single-threaded case, and a new 'type' of pool,
such that one can create real background pools of tasks. See code for details.

In previous code, worker would exit in case it gets awoken from a condition_wait() and
task queue is empty. However, there may be spurious wake up (either due to pthread itself,
or to some race condition between workers) that would lead to wrongly exiting a worker before
we actually exit the whole scheduler. See code for more details.
Metas are scanning all scenes duplis,
which can go into particle systems without an initialized derived-mesh.
For now just do NULL check, its not correct but real fix is not fitting well with current design.
Brush.toggle_brush was allowed to be an invalid pointer,
it worked for the one operator that used it - but in general bad practice,
requiring a lookup on every access.
Ensure the pointer is kept valid now.
Fix for T46494 wasn't working properly when de-selecting faces,
adjacent faces would remain selected but have unselected edges.
Logic here is admittedly rather fragile since it relies on both
selection functions and flushing afterwards.
Certain shapes could trick the inside/outside test.
An edge between 2 planar faces could be selected for detecting face-flipping (which failed).
While this could be prevented by skipping those edges,
use a method which searches for the outer most face-loop, then check it faces the center.
Works totally similar to backdrop in the compositor.
Requested by Sean Kennedy, but could be useful for lots for VFX guys.

Grabbing now doesn't 'jump' when shift is released (matching rotation modes).
This simplifies most logic for transform input,
where mouse input callbacks can choose to use the 'virtual' cursor,
which accounts for precision when shift is held.
Each time we setted the mass the own object gravity was divided by its
old mass (i.e you could convert you car in a flying DeLorean with a
simple mass car modification).
A note will be included in release notes due to retro compability
issues.
