Fix T45617: Map UV node produces image artifacts

Basically filtering was happening twice, first time by applying weights of EWA
filter itself and then by applying subpixel offset while reading pixel values.

Support subframe evaluation for scene strips

Useful when used with the speed effect.

Update of our *nix .desktop file.

Based on patch by Alex (AlexL) (T45927), thanks.

Make .blend file thumbnail reading simpler and more coherent, read/store them when reading in background mode.

Primary goal of this commit is to fix an annoying issue - when processing and saving .blend
files in background mode you lose their thumbnails, since it can only be generated with
an OpenGL context.

Solution to that is to read .blend thumbnail while reading .blend file (only done in background
mode currently), and store it in Main struct.

Also, this lead to removing .blend file reading code from thumb_blend (no need to have doublons).
We now have a small interface in regular reading code area, which keeps it reasonbaly light
by only reading/parsing header info, and first few BHead blocks.

This makes code reading .blend thumbnail about 3 to 4 times slower than previous highly specialized
one in blend_thumb.c, but overall thumbnail generation of a big .blend files folder only grows
of about 1%, think we can bare with it.

Finally, since thumbnail is now optionally stored in Main struct, it makes it easy to allow user
to define their own custom one (instead of auto-generated one). RNA API for this was not added though,
accessing that kind of .blend meta-data has to be rethought a bit on a bigger level first.

Missed version update loading in background mode

Fix T45926: Drivers fail in background mode

Scene evaluation was done before text blocks were registered.

Buildbot: Correction to previous commit

Previous commit didn't really disable cuda binaries for some reason.

Fix T45702: Editing smoke while viewport render and blender bug

Issue was caused by blender internal accessing data from DNA during rendering.

There's no simple solution to make stuff thread safe, so for now simply restart
rendering on frame update.

OpenSubdiv: Fix crash toggling edit mode with new depsgraph

OpenSubdiv: Tweaks to detecting whether geometry data is needed on GPU with new DEG

Buildbot: Disable CUDA binaries on win32

They started to give issues as well, need some dedicated time to look
into the issues.

Fix T45921: Screw modifier flips vertex normals

OpenSubdiv: Attempt to solve crash on certain GPUs/drivers

Fix T45920: Loopcut w/ shrinkwrap crash

Use correct size for BVH insertion

OpenSubdiv: Fix error found by PerfectionCat,

Use glew, not gl constants to detect presence of extensions.
glProgramParameterEXTi is part of GLEW_EXT_geometry_shader4

Fix T43826: Sculpt grab anchored fails

Regression caused by GSOC2013 merge f745564

DNA/IO: struct ghash lookup didn't set 'lastfind'

Internal inconsistency: lastfind was being checked
on every DNA_struct_find_nr call, but never set.

Gives minor speedup reading files.

Fix crash switching to rotate from edge-slide

Caused by own fix for T45458

Fix T45232: Cycles bake artifacts with transparent textures

The issue was caused by uninitialized ray used for composite and AO evaluation.

Can;t really think of "proper" ray configuration here, it's all a bit arbitrary
but think initializing the ray in a way so we look at the surface in a negative
normal direction is much better alternative to uninitialized ray.

Open for alternative suggestions tho.
