Merge branch 'master' into blender2.8

Fix typo error in Stroke Panel

Cleanup: use doxy sections for space types

Also use struct names in enum/define comments.

Cleanup: return types in stubs

Depsgraph: optimization of driver evaluation with many drivers.

WM: Use tool-system for setting brushes

This sets the tool instead of the brush, with cycling support.

Tool System: Utility to set the tool by name

Wrapper for the Python operator.

Implementing DPIX algorithm. (in progress, do not compile!)

Add primary refraction roughness modifier

(Does it need a better parameter name?)

Ref T54796

Motion Paths: Port motion path to draw manager (1/2)

Add keyframe drawing by baking the keyframe position in the motion path vert
cache.

Only remaining problem is that toggling the pose bone MOTIONPATH_VIEW_KFACT
needs a motion path recalc now.

DRW: Disable depth test for text drawing.

Fix OpenCL compilation error - BPT without SSS.

Merge remote-tracking branch 'origin/blender2.8' into temp-dynamic-overrides

Workbench: Highlights

Made the highlights darker (using the defaults of blender 2.7
- sharpness = 50
- spec color = 0.025 (I bumped it to 0.1)
- added a log2 to the frontal camera light to reveal more details of the
mesh

Tool System: optionally cycle tools in a group

Add the ability for key bindings to set a tool-group,
which cycles to the next tool when the tool is already active.

RNA: add tool index access

Needed for changing the active tool from Python.

UI: toolbars now redraw on tool change

Removed Object color from workbench. Added Highlights to FLAT shading.

UI: Move some panels to toolbar
