Brecht Van Lommel 0535d26e6d - Changed xz limit drawing to use same formulas as the limiting in the IK
module -- the previous method could be off pretty far.
- Added drawing of transparent surface for it, instead of just the border.
- Added "stretch IK", allowing bones not only to rotate, but also scale.
  The "Stretch" value below the DoF buttons is used to enabled this.

- Some code tweaking: slightly simplified computation of transform for IK,
  renamed chain to tree, removed unused pchan->ik_mat, ..

Internal IK module work:
- Do damping per DoF also based on stiffness, hopefully makes it converge
  faster with very stiff joints.
- Instead of having two joints types (translational and rotational), now
  all 6 DoF's can be enabled for one joint.
- Added limits for translational joints.
