Misc Render Features

Browse Source 
====================

- "From Dupli" option for orco and uv texture coordinates. For dupliverts,
  duplifaces and dupli particles, this uses the orco and uv at the point
  on the parent surface. Can for example be used for texturing feathers
  and leafs. Note that uv only works for duplifaces and particles emitted
  from faces, these are not defined at vertices.

- "Width Fade" option for strand render, to fade out along the width of the
  strand. Committing this so it can be tested, might be changed or removed
  even, if it doesn't give nice results.
