Blenlib: Assert when attempting to rotate point around vector and store result in the point

This isn't supported since there are subsequent reads to all point coordinates
after modification started.

Probably we need to create a temp copy of point, but that's like extra CPU
ticks.

Particles: Wrap insane amount of arguments to child modifier evaluation

Use single structure. It seems we will need to pass more information soon,
so better to do it via the structure.

Avoid unnecessary sqrt calls

Fix crash when rendering particles with cycles

view_layer is NULL when the render engine is created, this gets passed
around and ends up in this code causing a crash. This should be reverted
after the render engine api is updated to set view_layer.

Make particle edit draw mode a noop

Seems this was just a template, but that template painted everything
green. Not sure what this draw mode should do really.

Fix lack of particles updates and disappearing particles

The conditionals in particle code are... some sort of madness... I'm not
even sure what the correct behavior should be from looking at it.

In this case the path cache generation was being skipped in edit mode.

Tag update when using particle edit brushes

Fix crash with particle cut brush and other brushes

Why is bedit->data.context NULL?

Start bringing back particle edit

Its kind of broken, but have to start somewhere

Add versioning code to make particles with default size visible again

Due to changes in draw code particles from old files that may have had a
default draw size of 0 will not be visible. Old draw code would check
for this and adjust the size, however the unit for draw size has changed
from pixels to BU, and it no longer makes sense to have such checks.

This patch is to ensure particles from such files remain visible.

Merge branch 'master' into blender2.8

Cleanup: style, warning

Fix T54075: Align Objects fails w/ empty mesh

Cleanup: style

Fix T54072: Crash splitting edges

Merge branch 'master' into blender2.8

Cycles: restore Particle Info Index for now, keep it next to Random.

It seems to be useful still in cases where the particle are distributed in
a particular order or pattern, to colorize them along with that. This isn't
really well defined, but might as well avoid breaking backwards compatibility
for now.

Eevee: Fix broken AO and Contact shadows on certain platform.

DRW: Refactor: Less feature duplication with Gwn.

This removes the need of custom attribs for instancing.
Instancing works fully with dynamic batches & Gwn_VertFormat now.

This is in prevision of the VAO manager patch.

DRW: Add instance buffer manager.

This manager allows to distribute existing batches for instancing
attributes. This reduce the number of batches creation.
Querying a batch is done with a vertex format. This format should
be static so that it's pointer never changes (because we are using
this pointer as identifier [we don't want to check the full format
that would be too slow]).

This might make the original Instance Data manager useless but it's currently used by DRW_object_engine_data_ensure().
