Cleanup: Remove unused parameter

Add missing context to buttons_main_region_layout_too()

Fix building error, silence warning, stop double promotion

Revert "GHOST: GLX: Remove XInitThreads"

This reverts commit 7529690df38ced314d59af3b10c610e3fd56c807.

I tried to put manually add threading protection to GHOST around
Xlib calls but that did not fix the crashes. So reverting that
for now despite the performance implication on some system.

Preview: Add own opengl context to render preview images.

Cleanup: Remove excessive space

Give RigidBodyWorld collection a fake user

This prevents it from disappearing when the blend file is saved.

UI: redo panel would still start zoomed in at times

Cleanup: some remaining G.main's in COllada in 2.8...

Workbench: Code cleanup: Double assignment

Cleanup: remove BLI_frand ugly global random generator usage from compositor.

Merge branch 'blender2.8' into greasepencil-object

Transform: Suppress assert w/ vertex paint

UI: Get back Pivot point origin

This control was removed by error in previous merges.

This change is temporary while the topbar is redesigned.

Depsgraph: Make certain components NOT tag copy-on-write when they are tagged

Currently done for mesh batch cache update, and for base flags sync.
Those components do not need anything from original object, and hence
can skip CoW tag and have faster update after them used.

Depsgraph: Use dedicated ocmponent for object's base flags flush

Merge branch 'master' into blender2.8

GPU: consistenly use mipmap on/off in all draw modes.

This is important for good texture paint performance.

Cleanup: remove legacy GPU pass binding code.

Cleanup: minor style and naming changes.
