I'm not sure why the original implementation was only checking for equal
comparison but I'm doing the same here. It is a one line change if we
want to support LT/GT anyways.
Also "technically" we should compare the angles in the worldspace, since
different scales will result in different angles. Added as a TODO but
honestly I think this is overkill.
I'm using kdtree here but there is nothing preventing us from using a simple
float linked list with a sorting and finding "nearest" equivalents.
At least we are benefitting from bisecting as oppose to the original solution.
Also we need epsilon for the float comparisons.
This lets us do the most common shading switching with one shortcut. We keep
alt+Z and shift+Z for quickly toggling to lookdev and rendered mode and back,
it's debatable which settings deserve a dedicated shortcut like this.
The downside is that switching X-ray is a little slower, and that there is
some risk of accidentally going to lookdev or rendered mode which can be slow
to cancel.
We now treat Xray as being the mode where Limit selection to visible is off.
If Xray is OFF, Limit selection to visible is considered ON.
To allow 'see through wires' with solid shading (not Xray shading) we still
draw solid shading if Xray is ON with Xray Alpha set to 1.0.
Since shape keys are stored as raw floating point data, this
unfortunately requires changes to all code that works with it.
An additional complication is that bezier and nurbs control
points have different entry size, and can be mixed in the same
object (and hence shape key buffer).
Shape key entries are changed from:
bezier: float v1[3], v2[3], v3[3], tilt, pad, pad;
nurbs: float vec[3], tilt;
To:
bezier: float v1[3], v2[3], v3[3], tilt, radius, pad;
nurbs: float vec[3], tilt, radius, pad;
The official shape key element size is changed to 3 floats,
with 4 elements for bezier nodes, and 2 for nurbs. This also
means that the element count is not equal to the vertex count
anymore.
While searching for all curve Shape Key code, I also found that
BKE_curve_transform_ex and BKE_curve_translate were broken. This
can be seen by trying to change the Origin of a Curve with keys.

- Add Arc-Inner-Factor, to increase the inner arc radius from 0
(show as a disk).
- When showing an angle value, show the angle-end line thicker
(since thats whats being adjusted).
- Remove offset used by arc drawing which caused aliasing artifacts.
