GHOST: X11: Init multithread support.

This fix an assert on with Nvidia driver.

post merge compiling fixes

Apply Smooth and Random sculpt to UV rotation

Now it's possible apply the sculpt to the rotation of the UV texture.

Merge branch 'master' into fluid-mantaflow

Update strokes UV when change UV factor in color

Recalc UV data for any stroke that is using the color.

From review: Move depsgraph away from render layer and change render loop

Create depsgraph as part of the render loop and pass a render layer for the
render_to_image. Optionally we could create a single layered render_result
but why would we?

Depsgraph is created from scratch prior to rendering each frame.
So I got rid of most of the partial update calls we had during the render
pipeline.

Also, it's past the time to remove Blender Internal.

Note 1: Cycles doesn't build.

Note 2: Cycles seems to rely on an "empty" render function, where all the
required settings are passed to the update function instead. I would like
to have this cleared out because draw manager is assuming everything is
passed to render_to_image, but we need to have an API that makes sense
to all cases.

cleanup before master merge

GHOST: Add a new routine to unbind an ogl context for multithreading.

Merge remote-tracking branch 'origin/blender2.8' into temp-render-depsgraph

Fixup for border render changes

Although I fixed border rendering, I broke non-border rendering.

Issue introduced on: 0305fc30b3ba6a1b24e2c9c182ae2e76d553f341

Cleanup: comments.

Cleanup: use anonymous enum instead of defines for flags.

Eevee: add Principled Volume shader.

Eevee: add blackbody shader node support.

This replaces the blackbody to RGB code with the simpler and faster one from
Cycles. It's a little different but the other placing using this is the legacy
volume drawing, so no need to stay compatible with that.

GPU: fixes for string socket types in shader nodes.

These are not passed to GLSL functions, but should be used to load e.g.
a texture or attribute.

Eeevee: add temperature grid support, make color grid unpremultiplied.

This matches similar changes done for Cycles.

Merge branch 'master' into blender2.8

Cycles: add Principled Volume shader.

Similar to the Principled BSDF, this should make it easier to set up volume
materials. Smoke and fire can be rendererd with just a single principled
volume node, the appropriate attributes will be used when available. The node
also works for simpler homogeneous volumes like water or mist.

Cycles: change smoke color grid to not include density multiplied in.

This breaks backwards compatibility some, making smoke colors brighters
than before. But it is also more correct this way.
