Add an offset to ensure hair guide curves start on the scalp in export caches.

Properly set loop and poly indices in mesh samples where possible.

Replace callback for loop weights with a simple array, since these are cached anyway.

Extended hair follicle distribution function that allows geometry filtering.

Replace DerivedMesh with Mesh throughout hair code,

Replace per-vertex sampling weights with per-loop for more control (e.g. face maps).

Fix indexing for hair guide curve drawing.

Fix hair cache update flag combination, have to include dependencies regardless of cache state.

Only pass export cache to lower level draw functions, do export on higher levels.

Remove unused 'Axes' mode for follicle drawing.

Handle hair cache dependencies internally during invalidation to make partial updates more flexible.

Draw mode for hair guide curves.

Fix typo.

Missing forward declaration.

Make Mesh based eval the default for mesh sampling (generators unchanged).

Don't do implicit update in the hair export cache constructor.

Change particle conversion for mesh samples from DerivedMesh to Mesh.

Function for removing all guide curves in a hair system.

Add assert in psys function to ensure DM->Mesh conversion is not forgotten.

Cleanup: Temporarily removed all groom object type code, move it to a separate branch.
