DRW: Remove DRWTextureFormat in favor or GPUTextureFormat.

Because:
- Less redundancy.
- Better suffixes.

Also a few modification to GPU_texture_create_* to simplify the API:
- make the format explicit to the texture creation process.
- remove the component count as it's specified in the GPUTextureFormat.

Eevee: TAA: Use safe color when outputing the final color.

This prevent any NANs pixel to spear accross the history. This does not
mean we should allow NANs at all!

Merge branch 'blender2.8' into blender2.8-workbench

Overlay: missed in last commit

Fix error drawing with no object active

Overlay: Integration of TexturePaint with Workbench

UI: add weight paint brushes to toolbar

Workbench: Integration VertexPaint and WeightPaint modes

- Disable VertexPaint and WeightPaint for OB_MATERIAL and OB_RENDER. Users want to see the final result
- When in OB_SOLID, the active object should be rendered without any color. The lighting information is multiplied with the VertexPaint/WeightPaint color
- Removed the use_shading flag from VertexPaint and WeightPaint
- add method to check if render engine should draw without color (DRW_object_in_only_lighting_mode)

UV editing: Make 'Select Linked' work consistent to 3D View

Don't see a good reason for the old behavior, so better have it consistent.

UI: add vertex paint tools

Generalize logic to show the paintbrush as a tool so
different paint modes can use it.

Depsgraph: Fix missing node tree update when adding keyframes

Need to make sure animation data is copied from original tree to a copy,
it is NOT enough to only copy node socket values.

Fix: UI layout for "Pause" button on timeline header was broken (leaving a gap)

A recent change in the UI layout code probably broke how the scale_x
for layouts was getting handled. This was leaving a large gap
(and causing layouts to pop) when trying to scrub the timeline.

This commit fixes this with a manually-found value that largely seems
to get rid of the popping problem. There's still a little jumping (1-2 px)
but it's less distracting now.

big refactor for data, mesh, particles separation

replaced high res options with factor, particles and mesh now have separate solver, placed bake buttons in corresponding tabs in UI, fixed high res mesh

COW Fix: Material property update callbacks need to tag depsgraph for COW updates

Otherwise, trying to change color/material properties of EEVEE materials
that have been keyframed doesn't work until a new keyframe has been inserted.

NOTE: There's still some wonkiness if you edit more than one keyframed value
before keyframing (i.e. the other unkeyed value temporarily gets reset). But
that's more of a general COW+animation issue.

ANIM_apply_keyingset() - Tag modified datablocks for copy on write update for good measure

Fix some popup menus that don't support it refreshing and crashing.

Cleanup: Remove redundant parameter

UI: use "none" icon if loading fails

Workaround for issues w/ two column layout when icons are missing.

Also fix reloading icons when some values aren't valid.

Fix Eevee shadows not working in certain cases, after recent WM changes.

Fix sculpt ToolDef generation

With non-default sculpt brushes, tool generation could fail.
