Fixed lib-linking for hair edit settings brush and object pointers.

Basic Add tool for creating new strands in hair edit mode.

New simple storage method for single sample values.

Fix for uninitialized return value.

New mesh sample evaluation function for shape key data.

Generic raycast method for generating mesh surface samples.

Better feedback about valid sample from mesh sampling methods.

Support for common operators, keymap entries and radial controls for
hair brush settings.

Fix for OpenlGL state restoration after strand drawing, disable color
material option.

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.
