Log Message:
-----------
Render Branch: temporarily revert commit 29079 from trunk with particle
path changes. This is causing two problems (reported in tracker):
* hair doesn't move when transforming e.g. an armature parent
of the mesh emitting the hair.
* particle duplis on hair (for feathers) are not rendering.
Modified Paths:
