Curve cache for main groom bundle curves.

This stores interpolated cubic spline values for smooth curve rendering.
Local coordinate frames for sections are also computed alongside the cache.

Add UI script for groom data.

fix, possibly return an empty mesh and default psys index is 1 now

fix for randomized particle sizes

was accessing wrong indexes after particles died

added override with particle size option to mball remesher

remesh modifier can now remesh particle systems as well

Resolved issues with copy

WIP: Fix problems with stroke location

Still problems with reproject

Removed mem alloc for align in point_normals

Use general function to reproject stroke

WIP: Add status message and new keys

Still on progress

small fixes for acceleration map

refactored acceleration map, but might still have issues

also attempted to improve triggering (make exacter, but slow and error prone)

Remove warning message

WIP: Apply smooth to fill

WIP: Create stroke for fill

First step to create strokes

Extract function to be shared in other modules

WIP: First steps to implement Moore-Neighborhood algorithm

This algorithm is to detect the outline of a image. Now, the function only adds a blue line with the shape to the debug image.

Next step is use this array of points to create a stroke.

Merge branch 'blender2.8' into greasepencil-object

Cleanup: Remove debug lines and change some comments
