[Bf-committers] Question regarding Armature System

Personally speaking, I have a set of data which uses the X-axis as the
bone axis, and I think the Z-axis for the up vector. It was a real pain
to figure out how to convert the Quaternion Data, and Mesh Data, to
Blender's scheme. But I did. :-)
Just, in-general, though -- I like the idea of this being
user-selectable. Could you, perhaps, give me an "off-the-cuff" list of
what would need to change internally? At the very least I can stare at
it until I'm crosseyed. :-)
