Overview
Transformation (translate, rotate, scale) gizmo needs Parent Orientation space for working with bones. This PR adds in "Parent Orientation" to align the transformation axes to the object's parent space.
Objective.
A desired animation workflow is to work in parent space (for a targeted bone) rather than local space. To achieve this, in pose mode you can turn off "Local Location" and the bone will work in it's parent's space. However, the orientation gizmo doesn't reflect this, and still displays in the bones local space.
Gizmo in global space (which is the parent bones orientation)
Deselecting "Local Location" on the child bone:
Transformation Gizmo displays child local, but the desire is to show parent (I.e, global in this instance)
This Change
This Patch adds a new "Parent Space" Orientation option for the Transformation Gizmo.
For objects:
For Armatures:
Object Parent Space
Armature Parent Space. Always use parent space, even if local location is set.
Thankfully, no new transformation orientation code needs to be written, we can achieve the desired results be using the existing
transform_orientations_create_from_axis,ED_getTransformOrientationMatrix, andunit_m3methods. To do this, we check to see if the bone has a parent, if so, we use the bones pose matrix (pose_mat). This is done similarly for objects using the parent's object matrix (object_to_world).To document

Nice patch, cleaner than I would have expected from messing around with the transform system ;-)
Just two minor nags, no need to re-review after addressing them.
For my review I just looked at the code. Well, of course I also tried it out and it seems to do the right thing to me (it's now instantly one of my favourite transform orientations), but I'll leave the final judgement to an actual animator!

We should include review from the Modeling module, because they own the transform system. @ideasman42 are you interested, or could you pick someone else from the module?

The Modeling module have been completely silent about this, even though I asked for feedback twice. I've told them 'silence will be taken as implicit agreement after day X' and we're a week after 'day X', so let's thank them for their agreement and move forward.

For consistency, I think it probably makes sense to use the armature object's space for this as well. The armature effectively being the "parent".

From art/animation side, testing it on armatures and objects, I am happy with how it is interacting with the file.
💜 the comments in the low-level functions. Makes it so much easier to read & understand.
All I have left is a tiny nag about the comment style, otherwise it all LGTM!
Just land after addressing those.

And this one is more of a personal preference, but I'd remove the newline between the
