Only selected keys will get cleaned by the action and graph clean
operators

Cycles: Add some statistics logging

Covers number of entities in the scene (objects, meshes etc), also reports
sizes of textures being allocated.

Fix T44329: Blender Crash when rendering in 3DView.

This commit fixes two different issues actually:
* When view name is unknown/irrelevant, you should pass a NULL str pointer to
`RE_RenderLayerGetPass()`, not an empty string!
* `render_result_rescale()` would unconditionnaly free re->result (at the end),
even if it did not replaced it at all, leading to freed memory access later.

This is only a partial fix though, "CacheBuffer" (i.e. saving tiles in EXR files)
shall not be used in 3DView rendering, and yet it is here...

Move clean operator from action/ipo editors to the delete menu, now that
O key is bound to proportional editing.

Python API docs, don't hard-code sphinx themes

also set the theme to classic (as it was for 2.73)

missed last commit

rename _ipo -> _fcurve

Test: blacklist loading addons /w known problems

The test now runs without warnings

Multiview: remove option to preview the selected stereo 3d mode and error when quadbuffer not supported

This was causing glitches when switching from/to fullscreen modes (e.g.,
side by side to anaglyph).

As for the quadbuffer errors this is part of a more complete solution to
be committed later.

Multiview: fix crashes with pageflip mode - by Cédric Paille (cedricp)

Fix T31546 fragment program gets created every frame

That was really crappy indeed. Now we have a separate API
for low level OpenGL programs, plus a nice interface for GPU, also
removes some GL calls from main code as a plus :)

The source for the programs is also moved to nice external .glsl files
(not sure which extension convention GPU assemply uses)

Cycles: Fix BVH counter on mesh updates

Separate proportional editing options for graph and action editor.

Cycles: Fix wrong render result in certain configuration of render layer's surface/hair

There were some synchronization missing in cases when only one of those settings
was disabled.

Also added a render test for such configurations now.

Fix regression after multiview, basically we appended the wrong frames
to movie file.

We have to resort to use crappy workarounds with preview arguments again
since preview range is only for OpenGL preview.

Fix T44322: Crash when trying to render spotlight halos.

Trying to access rl's from full samples in non-full-OSA context (with uninitialized
sample index even :P ).

Caused by rBd5f1b9c2, probably a copy/paste typo or so.

Seriously... Fix building!

Fix part of T44320 selecting islands can fail.

Issue here is simple and has been fixed in other places such as
texpainting: Basically if face has different winding, do not calculate
it as adjucent to the other face, even if UV is identical.

This allows us to stack islands of symmetrical closed meshes on top of
one another and still be able to select the two identical island halfs
(provided the normals are correct of course).
