Cleanup: spelling

Add support for sculpt data.

Deduplicate evaluator implementations.

Cleanup, typo.

Precise comment for subsurf_data_eval.

Add check on the GPU backend, only OpenGL is supported for now.

Comment function as not thread safe.

Use type enum for evaluator type.

Reintroduce OpenSubdiv_BufferInterface to keep Blender's GPU code
separate from the generic OpenSubDiv code.

Merge branch 'master' into subdivision_work

Made changes as per revision suggestions

Merge branch 'master' into soc-2021-curve-fillet

Fix: Incorrect default values for the curve trim node

The default end factor should be 1. The proper value for the default end
length is somewhat arbitrary, but it shouldn't be zero.

Fix: Spline length calculation fails with no evaluated points

The case that checked whether there were evaluated edges was incorrect,
since two points are needed for an edge. Then also avoid running the
accumulation for an empty span.

Fix build error after previous commit

Incorrect renaming and use of enum after search and replace.

Cleanup: Fix/improve variable names and comments

Sculpt: Brush channels names are now lower-case instead
of upper case.

Sculpt: brush engine stuff

BrushChannels are now stored in linked lists
instead of simple arrays. This helps to
avoid memory corruption.

I had originally wanted to be able to pass
BrushChannels by value, but that doesn't really
work since they heap allocd data (the input
mapping curves).
