[Bf-committers] Drivers using FK-posevalues instead of actual result as reference?

[Tobias Oelgarte]

I'm a little bit puzzled. I was using a driven shapekey that uses 
rotational difference as source for the driver. The bone (lower arm) can 
be posed in FK and IK. But the rotational difference is only computed 
for the FK-Pose. The rotation that is stored for FK. But this is 
overwritten by a IK-Constraint.

Actually it does not use the visible difference between both bones (the 
reference for rotation and the lower arm), but the not visible FK-Pose. 
Is this wanted by design or a bug?

PS: Same applies for "Transform Channel" as driver-source.
