Add a new option that makes the Spline IK solver apply volume
preservation on top of the original scaling, considering the
pre-IK scale of the bone as the goal volume to be preserved.
This basically works similar to the Stretch To constraint, and
allows easily rigging a stretchy chain that uniformly follows
its parent's scaling.
Since the Stretch To behavior is more familiar, the new option
is on by default for newly created Spline IK constraints.
Perviously it was only possible to interpolate from the breakdown poses.
Now you can Push/Relax in regard to the rest pose as well.
For this only one keyframe is needed while the old modes needs two.
- This only applies to left click select. Right click select and the legacy keymap are unaffected
- You can still set the playhead from anywhere, using Shift-RMB, just like how you set the cursor in the 3D View
The hard-coded transparency of just 16 made it hard to see the markers
when the background was busy with keyframes (or strips in VSE).
The rename of the setting is in the following commit.

The main reason for this change is to allow setting the
active frame with the left mouse button, while still being
able to select e.g. keyframes with the same mouse button.
The solution is to introduce a new scrubbing region with
a specialized keymap. There are a couple of related todos,
that will be handled in separate commits.
Those are listed in D4654.
This solves T63193.

Most properties aren't altered by the evaluation of the bone,
and can be read immediately from its input operation. B-Bone
properties can be evaluated at the last possible moment.
This provides more freedom in using drivers to connect bone
properties: for example, it is now possible to read raw local
transform values via drivers from a bone that depends on the
reader bone via constraints.
Previously you could only orbit.
Apparently the order of the keys in the modal keymap makes a big difference.
Thanks to users Znio.G and Oskar on Devtalk who provided this solution.
This happened to be a bigger rabbit hole to hell than it originally seemed,
and there are higher priority design tasks to be handled (at this point high
priority design task is more important than high priority bug fix).
After talking to Brecht the decision was made to revert to the known isolated
issue, which will allow everyone in the studio work same as prior to last
Friday.
The remaining bits will be worked on after all the design tasks are out of
the way.

matrix inversion was changed in rB01c75c3765eb from own code to EIGEN
for performance reasons. EIGEN would return a zero matrix on failure
(resulting in the pivot always being at the object origin).
This brings back the "old" matrix inversion code (which has the benifit
of providing a partial solution which makes the local transform center
appear correct)

This allows creating hooks completely without the use of operators.
Also fix subtarget to actually recompute the inverse matrix.
In order to follow the vertex_indices_set function naming convention,
it is necessary to fix makesrna to avoid a naming conflict between
the function wrapper and the property accessor by adding a tag.

Do not iterate over degsgraph when overlays are turned off and
rendering via an external engine. External engines sync data
from Blender differently. The external engine
draws the depth buffer, but that is only needed for overlays.

After a lot of thinking about this, I decided that all operation modes
that I've tried over the past couple of years, including the original
2.79 one, have their uses after all. Thus the only reasonable solution
is to add yet another option.
The modes are:
- Strict: The current 2.80 mode, which overrides the original scaling
of the non-free axes to strictly preserve the volume. This is the most
obvious way one would expect a 'Maintain Volume' constraint to work.
- Uniform: The original 2.79 mode, which assumes that all axes have been
scaled the same as the free one when computing the volume. This seems
strange, but the net effect is that when simply scaling the object
uniformly with S, the volume is preserved; however, scaling the non-
free axes individually allows deviating from the locked volume.
This was obviously intended as a more or less convenient UI tool.
- Single Axis: My own variant of the intent of the Uniform scale, which
does volume-preserving if the object is scaled just on the Free axis,
while passing the non-free axis scaling through. I.e. instead of
uniform S scaling, the user has to scale the object just on its
primary axis to achieve constant volume. This can allow reducing the
number of animation curves when only constant volume scaling is needed,
or be an easier to control tool inside a complex rig.
