WIP: Animation: New Channel Transformation for Pose mode #107750

As per the discussion in Blender.chat, here's a blend file with an object (the cube) with delta transforms applied that cause the rotation and scale axes to be unaligned with the location axes:

delta_transforms_effect.blend

If you play with the location and rotation axes in the n-panel, you can see that their effects aren't aligned to the same axes, but all of the transform spaces display them as if they are. So I think making channel space available for objects would also make sense.

I also just generally like the idea of channel space being the "this always accurately represents the channels in the n-panel" space. So even if it were functionally redundant for objects (which I don't think it is, as in the attached file), it would still be nice to have there so the user can semantically specify "hey, behave like the channels" instead of having to guess which of the other spaces give that behavior.
