Merge branch 'master' into blender2.8

Cleanup: unused vars, correct bad (unused) logic

Cleanup: unused variables

UI: move 2d paint panels to topbar & toolsettings

Removed 'Tool' and 'Options' panels,
both these settings are quite obscure and
already available in the 'Brush' menu.

Fix top bar unified color & image paint brush

GP: Fix compiler warnings

fix: Collada: Error handler does not report Parsing errors and continues processing instead of stopping the import/export

Merge branch 'master' into collada

Depsgraph: fixes for the eval_flags API behavior.

- Use the original ID pointer for lookup in DEG_get_eval_flags_for_id.
- When the flags change after a DEG rebuild, tag the object for update.
- Instead of mixing int and short in different places, use uint32_t.

This fixes text not updating when a Follow Curve reference is set.

Fix T56172 Accessing COW data from RNA - Dimension

Also fixes T55769 Dimension Not properly work
and T56064 Blender crashes on selecting text-object

We decided to go to the easy way in the end, simply enforcing computing
BBox of all objects when using 'active' depsgraph, and copying back to
orig object (same as transform matrix, etc.).

GP: Add missing title for Armature modifier

GP: Rename Fixed type in Time modifier

GP: Add new Layer Pass Index filter to modifiers

Now the modifier can be filtered using the new layer index.

Also changed panels to put layers and passes filter always at the end of the panel.

Fix T57361: Creating a new scene with a full copy doesn't work.

BKE_scene_copy() & co. were pretty much doing nothing right...

Was a tough fight, but at least now they should behave a tad better (and
reported issue is fixed).

Proper fix is to fully rewrite that PoS, it was already a mess without
collections, now it's even hairier to handle properly, we need to use
modern new ID handling API for that (and maybe extend it a bit as
needed). But way too late to do that in 2.80.

Cleanup: Remove unused modifiers callback

Was only used by subsurf in the past years, it is unlikely
other modifiers will every need this any time soon.

Depsgraph: minor renaming and refactor of API for adding evaluation flags.

Subsurf: Remove edit mesh modifier callbacks

Those were used for partial updates during edit mode, which will
not be possible anymore with OpenSubdiv.

Optimization for OpenSubdiv would be to re-use topology refiner
if topology does not change. But this is something to be done
for both edit and object modes, no need to have separate code
paths for those.

This commit makes OpenSubdiv to properly work in edit mode.

Fix Python warnings when running in background.

Cleanup: fix compiler warnings.

GP: Add layer pass index to time modifier
