Fix In Front object selectability

We use the same trick as before but we now isolate it to a drawmanager
state to avoid loosing track of the state.

Fix crash caused by copy pasting!

Fix FXAA alpha issue.

We just take the full RGBA color instead of packing the luma in alpha.

Cleanup: Naming conventions, code clarity mentionned in review

Cleanup: Fix copyright year

Merge branch 'master' into tmp-overlay-engine

Overlay Engine: Fix overlay toggle not working

Overlay Engine: Only alloc extra depth texture if really needed

However this is a bit hacky as both workbench deferred and overlay engine
are responsible to ensure the texture is correctly allocated and framebuffers
are settuped.

Overlay Engine: Add Temporal Anti Aliasing

This add a very simple form of TAA for the overlay engine (in a similar
way as workbench does).
For now it only supports 4 samples but this can easily improved.

The update is not working all the time (i.e: armature edit/pose).

Overlay Engine: Add FXAA as base Antialiasing

This will be enhanced by TAA or other technique.

Overlay Engine: Fix selection outline antialiasing

Overlay Mode: Fix infront depth sorting

This is an improvement to 2.81. In front objects and extras are correctly
depth sorted.

The approach is to share an in-front depth buffer between all engines
so that workbench fill it with the infront objects depth. Then the overlay
engine can use it again to draw in front objects overlays correctly
occluded by the other "in front" objects surfaces.

Overlay Engine: Improve In Front pass ordering

This does not fix all the issues. For instance extra's are always drawn
occluded.

Cleanup: Fix debug Compilation warning

Overlay Engine: Wireframe: Put color evaluation in the shader

There are no more subgroups per color. Thus wireframes leveraging the
batching capabilities of DRWmanager.

The color mixing is also now done per vertex and interpolated instead of
per pixel. This might change the rendering a little bit.

This also fixes the xray rendering for wireframes and osx workaround shader.

Cleanup: DRW: Remove unused GPUBatches from Shape cache

Cleanup: DRW: Remove Hack of skinroot rendering

DRW: Fix an issue with instanced rendering and base_instance

Batches that are meant to be drawn with instancing cannot use ModelMatrix
indexing and must rely on the uniform (legacy) way.

Using the BaseInstance indexing would shift the instance attributes
received by the vertex shader which is not what we want in this case.

BLF: Remove use of geometry shader
