[Bf-committers] Armatures for beyond Release 2.4

So, I've been wondering -- what is really necessary to define a Bone 
inside Blender?  From the user Perspective, as well as the Python API, a 
Bone is defined as { Name, Parent Bone, Head Point, Tail Point, Roll }.

Is there a technical / mathematical reason a Bone could not be defined 
using { Name, Parent Bone, Bone Length, Quaternion from Parent, 
Translation from Parent }?  At least from the standpoint of the Python 
API, this would give the user much more control over rest position of 
the bone.

I was perhaps thinking the Python API for Editbone could be augmented to 
include (quick-example):
setLength( float len )
setRestLocation( Vector trans )
setRestQuaternion( Quaternion q )

Just a thought.  Thanks for all the hard work put in on the 2.4 release!
