=========

- Fix crash in particle transform with the particle system not editable.
- Particle child distribution and caching is now multithreaded.
- Child particles now have a separate Render Amount next to the existing
  Amount. The render amount particles are now only distributed and cached
  at render time, which should make editing with child particles faster.

- Two new options for diffuse strand shading:
	- Surface Diffuse: computes the strand normal taking the normal at
	  the surface into account.
	- Blending Distance: the distance in Blender units over which to
	  blend in the normal at the surface.
- Special strand rendering for more memory efficient and faster hair and
  grass. This is a work in progress, and has a number of known issues,
  don't report bugs to me for this feature yet.
