In object mode just draw simple wires for groom objects for now.

Simple operator for adding a single groom curve in edit mode.

Merge branch 'master' into soc-2017-normal-tools

Cleanup: Put includes in alphabetical order

Joining GP objects also merges + fixes animation data for the merged datablocks

Cleanup: Make it clearer which datablock/object we're dealing with

* gpd_act -> gpd_dst ("_act" could also mean "active one we're looking at now)
* gpd -> gpd_src (we sometimes refer to "gpd" as the active one we're working on)

Fix parameter list after merge

Merge branch 'blender2.8' into greasepencil-object

Cleanup: comments and reorganize

Apply all modifiers first

The previous commit was the Context missing as parameter and this was the reason of the errors

added option to only output verts, meta threshold max is 100 now

WIP: Initial code to apply modifiers

Copy Vertexgroup when join

The vertex groups were not included in the join.

do not invalidate cache when enabling / disabling centroid output

Fix duplicate layer name when join

added option to only output centroids as vertices

might be useful in conjunction with duplicated metaballs to have simple fluid-like behavior

WIP: Basic Join object operator for grease pencil

Still pending:

- Modifiers
- Animation data

Clean up after exiting groom object edit mode.

New draw engine for groom edit mode.
