Strand Render Simplification

============================

- Strand render now has options to remove child strands as
  the object's faces becomes smaller, in the Simplification
  particle panel.
- "Reference Size" is the approximate size of the object on
  screen, after which simplification starts.
- "Rate" is how fast strands are removed.
- "Transition" is the percentage of strands being faded out as
  they are removed.

- Another "Viewport" option removes strands on faces that are
  outside of the viewport. "Rate" again controls how fast these
  are removed.

- Strand render in Blender Units now has an adjustable minimum
  width. Below this minimum width, strands start fading out
  instead of getting smaller.
