fix for referencing freed memory when rendering materials (could crash material preview).

Fix #34863: bge.render.makeScreenshot from Blender was only saving PNG files,
while the docs said it followed the settings in the Output panel, other file
formats work now.

Benderplayer still only saves PNG now as documented, but I cleaned up the code
there to reuse existing imbuf functions rather than using own libpng code.

svn merge ^/trunk/blender -r55700:55776

Remove unused function.

It was only used for movie clips prefetching, no need
in it nowadays.

Use GLSL display for compositor backdrop and sequencer preview

Now only background images remained to be ported. Plus implement
GLSL for dithering and RGB curves.

Fix blenderplayer (missing stub...).

quiet warnings (building with -Werror)

metaballs were not scaling/rotating about their own centers when V3D_LOCAL was used.

Changes to cache invalidation policy for movie clips

- When changing clip in clip editor, remove all frames
from it's cache to free memory for new clip.

- When changing proxy render settings, free cache as well.

Clip editor prefetch changes

Made it an operator instead of automatic prefetching.
Filling the whole memory with frames is not always
desired behavior.

Now prefetching is available via P-key, or from Clip
panel in toolbox or from Clip menu.

Also enabled prefetching for non-proxied movies.

fix [#34802] Individual Transformation Confusing in Edit Mode

Individual transformation now works in editmode mesh faces/edge, armature bones and metaballs.

improved method of getting the tangent axis from a bmesh triangle,
rather then getting the longest edge, get the edge which which is most different from the 2 others ends up giving more useful results: for an isosceles triangle it returns the base weather its longer or shorter then the other sides.

fix [#34860] View in Weight Painting mode no longer rotates around active bone

code cleanup: use bools, (float)sin/(float)cos -> sinf/cosf, more meaningful var names.

Fix for [#34754] "Revision 55527 provokes glitchy GLSL shadow map rendering" reported by Alain Ducharme. Per material uniforms and per object uniforms are now better separated.

code cleanup: use bools in UI and WM code, quiet some shadow warnings, remove unused function uiEmboss()

Fix #34625: duplivert/face rendering with modifier could crash accessing UV and
generated coordinates on the original mesh, after the change that made duplis
take modifiers into account.

Fix for Freestyle face marks not effective with the Mirror modifier.
Reported by IRIE Shinsuke through a branch code review comment, thanks!

Fix #34700: orthographic camera DOF was still not working correct.

Apparently zoom in clip editor was broken

Also silenced some warnings in glutil.
