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

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.

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

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.

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.

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.

New image file icons for hair brush tools and an according tool enum in
the Brush RNA.

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

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.

Copied high-level operator code from the paint/sculpt system as a basis
for brush-stroke operators in hair edit mode.

Hopefully this can help avoid some redundant code and ensure consistent
keymapping etc.

Missing bmesh include folder for hair editor in scons.

Apply the hair matrices when converting from particle keys to bmesh,
so the edit data is consistently in object space.

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

New drawing code for hair edit mode.

Conflicts:
source/blender/editors/space_view3d/drawobject.c

Removed deprecated code.

Free strand edit memory after use.
