[Bf-python] More on Bone.getRestMatrix() and bones

[Ken Hughes]

I've decided to try torturing myself and have started looking into
what the bone/armature code does (not just the Python wrapper, the
actual code).  This post is aside from that.

My understanding, based on the Blender documention on armatures objects:

http://www.blender.org/modules/documentation/htmlI/x7107.html

is the rest position is the initial position of the bones: without
posing or animation.  If so, isn't this what getRestMatrix() should
be returning?  From bug #2230 (Nick Lawson's bug), the rest
matrix being returned after animation is wrong, but seems to me
like it should never change.  There should instead be another
method (at least) which returns the just the pose matrix?
