Sanity check for strand root/tip checks, now supports single vertices.

MSVC compiler cannot handle standard C code.

Conflicts:
source/blender/editors/physics/particle_edit.c

Fix scons build files for new hair edit code parts.

Fix for hair-to-particle export: need to set weight=1.0 for hair roots,
since the particle system uses this for pinning them to the mesh.

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

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

Fix for uninitialized return value.

Better feedback about valid sample from mesh sampling methods.

Conflicts:
source/blender/editors/object/object_shapekey.c

New simple storage method for single sample values.

Generic raycast method for generating mesh surface samples.

Conflicts:
source/blender/blenkernel/intern/mesh_sample.c

New mesh sample evaluation function for shape key data.

First selection operator implementation for hair edit: circle select.

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

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

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

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.

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

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

Implemented basic cursor drawing for hair edit mode brushes.

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.
