GHOST: Fix uninitialized values.

Cleanup: remove unused DAG_EVAL_PREVIEW mode.

Cleanup: remove object.is_visible.

Depsgraph already iterates over visible objects, and since this was only
valid for objects evaluated with the depsgraph it was confusing.

Fix incorrect object selection test in outliner and rigid body.

Fix T55436: crash with point density and shader tweaking.

With copy-on-write we can no longer assumes the point density data is
available after Cycles synchronization with Blender data is done. So
force it to be loaded earlier, even if it's not great for interactivity.

Fix merge error in 908b696, removed files were accidentally added back.

GHOST: Fix uninitialized var

Was causing crash on startup.

UI: split left/right header buttons

- Added flexible separators to
Clip, Graph, Dopesheet, Image, Node, Timeline, 3D View.
- Added graying out for Proportional Editing
menus to avoid popping when right-aligned.
- Slightly re-arranged some controls,
so they can be on correct side of the separators.

Patch by @billreynish

Fix: Remove UI_BLOCK_MOVEMOUSE_QUIT from popovers

This was causing driver editing popovers to just keep disappearing
whenever you accidentally moved the mouse away, making the popovers
there nearly useless.

After testing with the other popovers we have in other places, I don't
really see why we needed this flag enabled in the first place. You can
still switch between popovers in the topbar by mousing over the others,
and if you want to dismiss without clicking to escape, you can go over a
standard menu instead OR just move back towards the button that spawned it.

Let's just test this out for a while and see how it goes. Maybe we don't
need a more invasive solution here...

Workbench: API Changes

- merged matcap and studioLight api

Cleanup: remove moar ugly G.main usages...

BKE_image was an ugly nest, could fix all but the ones from compositor,
so moved ugly G.main there, at least we know where the Evil is that way ;)

Fix T55440: Pose Mode Crash

Fix separator element for headers with multiple directions

UI: Separator spacer

This support layout.separator_spacer() to be used by headers as a way to
dynamically separate the ui buttons.

Right now no UI file is changed, though we can use this right away in the
timeline, and shortly after in the viewport header (moving settings from
the topbar to it).

Original design by William Reynish.

Render: Create a separate gl context for rendering.

This should take care of all the threading stability issues some people
are reporting.

GHOST: Delay opengl context initialization

This way they can be init in their owner thread. Contexts should not be
shared accross threads. Once you make a context active on a thread it is
owned by the thread.

This commit only have the GLX backend updated but should not break orther
platform.

DRW: Rename ogl_context to gl_context

We might not use opengl forever :)
