Add translation context and idcode entry for the new ID type.

Make sure MAX_LIBARRAY is large enough (also add a static assert for this).

Add new Groom ID type to use for groom objects.

New OB_GROOM type for hair editing objects.

Use material slot index instead of a direct Material pointer.

A Material pointer would be a nicer way to assign a hair material,
but unfortunately that does not work well with the context-based material
lookup of the node editor. There is no selection of an "active" modifier,
so the node editor will never display the material (unless it is placed
into a material stack as well).

Material pointer in hair systems.

Simplified API for generating hair follicles with a fixed max count.

The final count is inversely proportional to the min_distance, so using that
as a user variable is difficult to control. Instead we just use the overall
count as the single variable now.

The actual final count will be less than this maximum count, because the
theoretical limit is never reached in practice. The min. distance could also
be stored as a result of the hair generation as feedback for the user.

Merge branch 'blender2.8' into hair_guides

Fix strand vertex init loop, use correct stop index.

Need to call the subdiv function also for subdiv==0 to initialize vert positions.

Extend the fur generate modifier to also create guide curves.

More meaningful flag names for hair system changes.

Remove unused code, this has been replaced since.

Fix for overflow of cell_index in the Poisson disk sample generator.

Using a single uint as combined cell index only leaves ~10 bits per
coordinate axis, which quickly leads to overflow for higher densities.
Now use 3 ints so that the sampling grid can have sufficiently small
cells.

Additional pass in object mode for drawing hair follicles and guide curves.

Fix memleak from unfreed local array.

Struct for hair draw settings.

This is outside of the hair system itself since it only affects drawing.

Operator for generating hair follicles of the fur modifier.

Fix mesh sample inner loop for poisson disk generator, returned false always.
