Included DPIX Code, prevent compile.

Cycles: Cleanup: Don't use return on function returning void

UI: use subpanel for particle emission source, as an example.

UI: add subpanel support.

In the Python API, any panel becomes a subpanel by setting bl_parent_id
to the name of the parent panel. These subpanels can contain advanced or
less commonly used settings.

Added support for extending sharp edges with bevel

Support material slots in Groom type objects.

UI: move Cycles device to Performance panel.

Some cleanup/refactor from code review.

Snap groom curves to the scalp surface in the curve cache.

This also makes sure that guide curve (which are generated using the
curve cache) run inside the actual bundle volume. Otherwise they might
get an offset that aligns the root, but makes them diverge in non-root
sections.

Merge branch 'master' into blender2.8

Cleanup: correct variable name, doxy sections

GPUTexture: Fix memleak in orphaned texture management.

DRW: Hair: Add additionnal subdivision smoothing support.

Only use catmull-rom interpolation for now. It's smoother and does not
exhibit artifacts.

Merge branch 'blender2.8' into greasepencil-object

Workbench: Fix memleaks.

Wireframe: Optimization for intel GPUs.

Intel GPU take more advantage of the geometry shader than other vendors.

Using a simple geom shader approach in this case is more performant.

Cleanup: add argument names to screen callbacks
