Code cleanup / Cycles:
* Use M_2PI_F in more places and do multiplication instead of division in gradient texture.

Code cleanup / Cycles:
* Re-use already defined Westin closure class.

Fix #35443: Animation player doesn't play some movie formats

Need to initialize FFmpeg for animation player.

This is a bit confusing, but the only way to do this
properly and clear is to call IMB_ffmpeg_init from
playback_mode command line callback.

This is because this callback is blocking and
"usual" FFmpeg initializetion (which happens after
command line parsing) was never called.

Could be switched to separate FFmpeg initializtion
and debug level set but let's keep simple for now.

Fluid simulation manual number of threads option now doesn't set the number
of threads to the number of cores when the fluid is created. Rather it is now
set to 0 which means "use the number of threads specified for the scene".

Fix compiler warnings with westin OSL code.

Fix to show numpad . instead of NDOF fit as first shortcut key in menus.

Related to #35452: show warning when unwrapping object with negative scale, same
as we already do for non-uniform scale.

Fix build error after removing return value from MEM_freeN.

code cleanup: remove callbacks only added to wrap MEM_freeN

remove return value from MEM_freeN, it wasn't used anywhere and was cast to a different function signature. (which evidently works but error prone).

fix own bug [#35451] Extrude -> Grab -> Cancel -> Crash

code cleanup: scons - binreloc include was copied all over the place for no reason, -pthread too.

code cleanup: split scons includes onto multiple lines, reduce chance of include conflicts later on.

Fix: smoke noise tile was saved in Blender executable directory, which is often write protected on modern systems.

This caused high resolution smoke to always regenerate new tile when domain was reinitialized, slowing down especially adaptive domain simulations. Now noise tile is saved in Blender temp directory instead.

code cleanup: replace PARALLEL define with _OPENMP

Cycles / Wireframe node:
* Added a wireframe node (Input category) to get access to Mesh wireframe data.
The thickness can be controlled via a "Size" parameter, and is available in world units (default) and screen pixel size.
* Only the triangulated mesh is available now, quads is for later.

Math Node:
* Added a Modulo operation to the math node, available in Compositor, Shader and Texture Nodes.

no need to add own define for openmp.

Cmake / Fluids:
* Possible fix for Fluid threads UI not being shown with cmake builds.

code cleanup: rename bmesh operator files to be more consistent
