Cleanup: simplify RNA names

Fix crash in combing after changing scene property

OpenSubdiv: Changes in C-API

- Made OpenSubdiv_GLMesh private
Previously, it was still accessible via C-API from C++ code.

- Don't implicitly refine evaluator when updating coarse positions,
now there is an explicit call to do this.

Allows to first apply all changes to the coarse mesh and then
refine once.

- Added coarse positions update from a continuous buffer with given
starts offset and stride.

Allows to update coarse positions directly from MVert array.

- Refiner is no longer freed when CPU evaluator is created.
Allows to re-use refiner for multiple purposes.

UI: don't change scrollbar size on mouse move, only fade.

It's not necessary to do both, and trying to hit a target that changes
size is annoying.

Fix Use Nodes not working for Cycles lights.

Cycles: Switched CPU cryptomatte to use unordered_map instead of map.

3D View: any view axis also showing grid

Setting accidentally impacted in ortho view.

Merge branch 'master' into blender2.8

Cleanup: duplicate versioning block

Merge branch 'npr_tess' of https://github.com/DarkDefender/blender into soc-2018-npr-tess-modifier

Fix empty-images not using selection color

Manipulator: changes for overlay options

There are now 3 categories in the overlay popover:

- Navigation
- Active (camera, lamp... etc)
- Tool (manipulator)

The user preference for mini axis now controls if the mini axis
displays minimal or a full-interactive widget.

Part of design: T55863

Make vertex wig sampling reflect the method in the paper

Added time reporting and optimized osd_eval creation

Revert "Transform: default constraint to user orientation"

This reverts commit 81210103104980c9052de491a0b4defd003c2d1e.

After user feedback this has the downside of having no predictable
way of transforming in global space.

Since toggling between global/user is reversed when global is
the user axis.

Fix problem with Eraser cursor

The blend modes were using the GPU functions but the parameters were the old GL mode.
