Eevee: SSR: Fix ssr nor working in ogl render.

DRW: Fix boolean uniform lenght.

Boolean uniform needs to be 4bytes long for opengl.
Use "int" for every bool you want to pass as a uniform.

Eevee: Fix issues with alpha blending

- Hashed Alpha materials were outputing their alpha values even if the final pixel has no blending and thus no transparency.
- Opacity was not clamped when using "add closure" nodes.

DRW: Fix incorrect blending functions.

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

Merge branch 'master' into blender2.8

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

tests: limit public API in view_layer_common

tests: replace boiler-plate with util function

This crept back in somehow!

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.

Outliner/Collections: Remove selected objects operator

This is part of T53495.

Outliner/Collections: Add selected objects operator

This is part of T53495.

Outliner: Right mouse menu for collections editing

Static assert for correct strings from context mode enum.

Adding new context modes requires adding a string in CTX_data_mode_string,
but there is no error when omitting this other than panels using
incorrect contexts. The static assert should help detect simple
missing strings at least to avoid confusing errors.
