Implement particle velocity and acceleration visualization

Merge branch 'master' into blender2.8

Fix T51534: Alembic: added support for face-varying vertex colours

Houdini writes vertex data in a different format than Blender does; Houdini
uses "face-varying scope", which means that the vertex colours are indexed
by an ever-increasing number over all vertices of all faces instead of the
vertex index.

I've also merged the read_custom_data_mcols() and read_mcols() functions,
because the latter was only called from the former, and the changes in this
commit would add yet more function parameters to pass.

Alembic: reduced code duplication in read_mcols()

A big chunk of code was copied between the if and else bodies. By using
a boolean to store whether the c3f_ptr or c4f_ptr should be used, the
in-loop condition is kept as simple as possible.

Alembic: split up read_custom_data_ex() into read_custom_data_{mcols,uvs}()

The read_custom_data_ex() function was basically two functions inside
if/else bodies.

Add PovRay file extensions to our 'textual' file filtering.

Fix some POV keywords not colored correctly.

We need to ensure longer keywords are catched first, when there are
shorter subsets of them in keywords list as well!

Eevee: Disable directionnal lamps shadows

Use pointers to actual data for particle uniforms

This makes particle color uniforms point directly to material color, and
particle size uniforms point directly to ParticleSettings size.

Use custom shader for dot particles

Rename/move particle shaders

Draw Manager: Prevent errors when overwritting the instance batch.

DWM: Add short to float / int uniform function.

Short values are common in DNA, this enables using them directly without storing temporary float somewhere.

Fix T48668, bevel mistake on presumed reflex angle.

Note: the angle in bug isn't really reflex - using the vertex normal
for this test isn't always right, but usually is. At any rate,
shouldn't try to put vertex on edge between if a reflex angle.

Create new shading group for each psys

Revert "Implement UBOs for particles"

This reverts commit 845732652fa7a3d3a053006d30a76ea39fdc3c47.

Stupid mistake in material access optimization

Make msvc2015 happy again.

Looks like that wanabe compiler does not support more than a few tens of
if/else conditions...

Fix T51319: Alembic export crash w/simple child particles if Display value < 100%

This was two-fold.

1) The export used viewport settings to obtain the particle cache, rather
than render settings.
2) The child hair writer tried to obtain UV-coordinates from the parent
chair, without checking whether those were available in the first place.

Cleanup: Make Gawain code style more consistent

Not as if i'm totally fine with such style, but i'd better be consistent
with whatever the project is using.
