Merge branch 'master' into cycles-x

Cleanup: Use iterator rather than recursive functions

Also add missing `_` suffix for protected member variable.

EEVEE: Film: Make smooth transition not rely on dtxl->color persistence

This is a needed change for the viewport compositor. The compositor
needs to draw to `dtxl->color` to have correct overlay / background
composition.

The solution here is to have a separate buffer that keeps the first
sample we blend from. This increases VRAM usage but it is the most
elegant option.

WIP - Render set of thumbnails that are "guaranteed" to exist.

They are not really guaranteed though, just very likely to exist.

Also math is incorrect when handle is extended beyond content, which is not too nice

Bring back pre 2.8 scrolling acceleration

Up until the 2.79 release, we'd use our own acceleration method for scrolling
on macOS. Since then we rely on macOS to do this for us, but turns out it does
a worse job, at least for our needs. This is an experiment to bring the old
behavior back.

Viewport Compositor: Initial commit

This introduce a new compositor engine. It applies the compositor
nodetree onto the render result in the viewport using GLSL shader.

For now it only very few nodes are supported and only the combined
pass is passed to the evaluation pass.

This reuse almost the same pipeline as `GPUMaterial`.
