Show selection state of hair vertices with the usual theme colors.

Apply the same weight profile in the comb tool as in particle edit mode.

The comb tool will likely get a complete overhaul, but until then it
should just behave like the old tool.

Fix for brush radius, the Brush.size property is actually the radius and
not the diameter.

Added back different selection modes (strands, verts, tips) for hair
editing.

First selection operator implementation for hair edit: circle select.

Use the "official" brush size calculated by blenkernel and subdivide
the stroke step to avoid tunneling.

Filter affected hair vertices in edit mode based on the brush size and
z depth.

Primitive hair lighting in OpenGL solid shading, cleanup of strands
drawing code for edit mode.

The lighting uses the same method as the particle hair, interpreting
strand direction as the normal. This is nowhere near realistic hair
shading, but doing this with line shading alone in the fixed-function
pipeline is probably not possible. A GLSL shader could be used instead
for a more realistic alternative as part of the viewport project. At
least this simple shading mode gives some orientation feedback while
editing hair.

Implemented basic cursor drawing for hair edit mode brushes.

Display basic brush properties in the toolbar for hair edit mode.

Constrain hair root vertices to their mesh location after applying tools.

Make sure tool input data is in object space.

Nicer vector math for mouse coordinates.

Simplified first version of the hair stroke combing functionality.

Stroke tools will be categorized by the hair elements they operate on:
vertices, segments or strands (roots). In addition to that a filter
function defines the influence of the brush. This should be defined by
the other brush settings and be largely independent of the main tool
mode.

Enforce hair constraints (constant segment length) after applying a tool.

Currently uses the same approach as old particle edit mode (rescale
hair segments from the root on). A more sophisticated approach using
least-square error minimization of the displacement could yield better
results.

Lots of small fixes for paint system quirks to make hair brushes work
in the UI.

Define hair edit settings and brush types in the RNA, similar to paint
and sculpt settings.

source/blender/makesdna/DNA_brush_types.h

Fix for GL buffer size for edges, needs to 2x for two vertex indices.

Revert previous hair edit operator scaffolding and port over the old
operator for strokes instead.

The paint system is much too complicated and does not add any real
advantage at this point.

Calculate some basic info about mouse strokes and context and pass it
on to a general hair tool function.
