When modal map was introduced, left out handling of what
happens when bevel is made active tool in toolbar and user
starts bevel by clicking and dragging.
Also added keys for toggling harden normals,
and cycling through miter types.
Still to do: add some shortcuts for affecting the
spread value for arc miters.
The old function was numerically very unstable for 2 reasons:
computing the square and then subtracting the results.
In the example in T60935 all precision was lost and it returned the distance 0
for all points.
I also removed the `depth` parameter since it wasn't used and computing
it would have made the code more complicated.

This complicated handling of undo steps in a generic way
especially switching between undo systems that stored data to ones
that accumulated changes.
Now each undo system must treat it's steps as check-point,
internally it can apply/rewind changes.
This commit also fixes projection paint where the object mode wasn't
following the undo steps.
BF-admins agree to remove header information that isn't useful,
to reduce noise.

This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
The inset operator uses 0.01 as default for the inset.
When the face is very small than this default is very confusing (see T60226).
The simplest fix seems to be to just use 0 as default.
This is similar to the extrude operator which uses 0 as default as well.

Will document the new options in release notes, then in manual.
Still a bit of work to do on the bulging shape that appears
on cube corners if using arc inner miters, but will do that later.
Also need to do something smarter in clamp overlap.
Harden normals causes normal splitting, which will not give the
appearance expected due to autosmooth unless some edges are sharpened,
so this change fixes that. Also bevel tool will turn on autosmooth
if not already on if hardening normals.
The intention was to flip normals when extruding in the opposite
direction, however the sign of the angle isn't meaningful unless
the geometry center and region normal are taken into account.
Disable, may add back in a way that works more predictably.
Move the bevel hardening code all into bmesh_bevel.c.
Based on user feedback, rewrote the bevel hardening algorithm
to be more what users want.
Based on user feedback, changed the UI, removing some
not-useful options. Now hardening normals while beveling
is enabled by a simple checkbox.
Now setting face strength gives options for which faces
get their face strength set.
The root of the problem is that KnifeTool_OpData->colors was not init in
some cases. But the reason is unknown as it seems to be random and the
init function was always called.
So instead on init the color only once, we query the colors each time
we draw the knife points.
The overhead of this approach is negligeable.
