Eevee: Make the background black when rendering without sky.

This prevent some bad blending when using transparent materials.

OGL Render: Use float buffer instead of byte buffer.

We need to remove all transform to display during rendering for this to work. The float rect is then color managed when displayed.

This makes all interface colors wrongly displayed because they should be color managed when rendering.

GPU_offscreen: Add option for high bit depth.

This way we can render in HDR and read the real pixel values.

DRW: Fix small changes to transparent background.

Fix changes introduced e3ef782af5d5

Eevee is in charge of rendering so it should be its task to have it's buffer initialized

Validity flag in bundles to indicate when they are validly bound to the scalp.

This is updated through the depsgraph. Currently just checks for existing scalp
object and vertex groups, eventually will perform actual tracking of the mesh
surface to ensure the groom follows changes of the scalp mesh.

Merge branch 'master' into blender2.8

Display the scalp vertex group as the main identifier of bundles in the list.

RNA collection and UI list for groom bundles.

WIP: Improve interface for fill brush

Now is possible to delete it and can have several of them.

Fix uninitialized stack use in rna diff override

Fix T53586: Surfaces collapse when joined

Fix T53637: Keymap from app-template ignored

Addon's were also ignored

fixed some crashers

first attempt of deform mblur with remeshed particles, but it still has issues

tests: limit public API in view_layer_common

tests: replace boiler-plate with util function

This crept back in somehow!

Cleanup: Remove dead code, Fix incorrect labels, and Make things more Pythonic

Fix FOREACH_SCENE_COLLECTION/FOREACH_SCENE_OBJECT for nested collections

This fixes any function that relied on these iterators such as:
* Outliner Same Type
* Metaballs
* scene.objects

We were not considering the collections when there was collections nested
to the collections nested to the master collection.

It includes a unittest.
