These modes were missing.

Fix Direct coloring calculation

/facepalm

Ref T54796

Generic Viewport Panel for Materials

Is enabled for all render engines as workbench will be rendering
SOLID/Texture modes and uses these settings.

Cleanup: style/whitespace

Also use 'uint'.

Cleanup: redundant check

OSL: initialize geometry as part of the setup

This needs a custom OSL closure. Now it renders, but the colors don't make sense

Fix more of nirved's OpenCL errors

Thank you nirved for finding and explaining them!

Ref T54796

Fix selection randomly failing with border render.

We no longer user scissor for 3D viewport drawing, and some selection
code assumed it still. This also cleans up unnecessary scissor test
switching, we only have it temporarily enabled now.

Merge branch 'blender2.8' into greasepencil-object

Merge branch 'soc-2018-volumes' of git.blender.org:blender into soc-2018-volumes

make.bat: fix support for building with just the build tools installed.

Initial working implementation of tiling for sparse grids.

Fix Cycles UI script error with denoising.

Fix Cycles viewport render stuck with curve objects.

We should solve this better by making the depsgraph convert all curves to
meshes, for now ensure we don't to depsgraph tags during export.

Depsgraph API: renaming, more granular update information.

* depsgraph.ids: all evaluated datablocks in the depsgraph
* depsgraph.objects: all evaluated objects in the depsgraph
* depsgraph.object_instances: all object instances to display or render
* depsgraph.updates: list of updates to datablocks

Render API: rename some API functions back to earlier names.

Their purpose is the same, no reason to break API compatibility here.

UI: use split property layout for some panels

Object, render, scene properties now use split-property layout,
also cycles interface.

Patch by @billreynish w/ minor edits.

Cleanup inactive code

Cleanup: quiet warning

UI: fix property split w/ color buttons & empty text
