Broken: BuildBot 2.73.1 8a28895 (Jan. 3rd, 2015), also BuildBot 2.72.2 5c6e33 (Nov. 11th, 2014)

Short description of error
If I set a shrinkwrap constraint on a bone and set it to project in the +Z direction in pose space (the armature object's local space, if I'm not mistaken,) it will instead be projected to the target in the +Z direction in the bone's local space.

Exact steps for others to reproduce the error

Armature_Shrinkwrap_Axis_Misalignment.blend785 KBDownload

Observe the behavior of the three bones in the same armature - all are meant to be projected to the landscape above, but the one whose local axes aren't aligned with the armature object's axes isn't projected up when the constraint is set to project it in the pose space's +Z direction. It is instead projected sideways, in the +Z direction in the bone's local space.

Yeah, would look like this setting is not used at all actually… checking.

So, own fault in rBb154aa8c060a60d476970bb8b8fab3912a2afc22, to fix T42447… Now have to find a good solution for this, and stop being stupid (like forgetting constraints can also be used for bones xD ).
