OpenSubdiv: Initial work towards UV maps support

This lands basic test of pass UV coordinates to the coarse mesh
via evaluator C-API and implements all the needed interpolation
in the GLSL shader.

This code is not used still because GLSL shader is not in use
because enabling it will make it impossible to run anything on
the older cards.

Still need to do some runtime check for this..

Fix some undo issues with paint curves.

Fix issue with multiple materials not displaying colors correctly.

OpenSubdiv: Update GLSL code to use geometry shader

This bumps GLSL requirement for the GPU, but this is the only way
we can support fare-vertex attributes. Shader currently supports
solid draw only but it've got lighting model hooked up.

This gives quite noticeable slowdown on my gt620, but this card
is not really something powerful and likely code could be improved
later.

This also allowed to have proper normals for flat shading.

For now the code stays disabled for until some runtime check or
so is implemented.

TODO: There are some matrix functions which are currently simply
copy-pasted from the blenlib, would be nice to clean this up.

Finalize transform for paint curves:

Use own simple operator for slide transform, allows to return pass
through and set the cursor.

Cursor pivot not yet supported for paint curves, it will be next.

Merge branch 'master' into opensubdiv-modifier

Fixed the memory leak bug, the bug that caused trimmed vertices to linger, and the bug that separated connected triangle faces produced with alt+c.

Make selection of paint curve handles much easier.

Fix generating temporary files with prep binary, also comment out include of hgnfo header for now.
- I just uncommented failing code
- dunno whats up with hginfo, guess thats from external source versioncontrol of manta (?)
- pls disable openmp, due this branch was not merged lately and misses omp cmake fixes
I checked all is compiling fine now

Themefy paint curve colors, some tweaks to make selected paint handles
more visible.

Functionality Review:

Fix: Rotating/Scaling a handle would not use curve center as pivot.

Functionality Review:

Bugfix: Paint curves not functioning in weight painting.

Palettes:

Functionality review:

Include "active palette color" concept, marked by triangular widget.
This is set when adding and selecting a palette color.
Add explicit delete operator that removes the active palette color.

Defocus + VarSizedBokeh

Fix for bokeh blur

Added SAMPLING to the Bokeh blur.

correct prep binary location, debug messages instead of prep step
