Some knife fixes. Avoids duplicating verts; better handling of cut-through ortho.
...
Now cut lines detect vertices that they pass (almost) exactly over
and snap to them, to avoid making verts vert close to other ones.
Added radius arg to BKE_bmbvh_ray_cast so that can detect an obscuring
face when the ray might otherwise go exactly between two triangles.
Needed an isect_line_tri_epsilon function for similar reason.
Fixes last part of bug #35002 . Other knife bugs still present but
getting this commit in now before continuing bug fixing.

Looks like no scaling is done elsewhere on blender for this code. I hope
this bug is squashed for good.

* Fix for #31581 . The issue was that we scaled the face prior to
...
projecting it. The original paper suggests to simply interpolate between
the two points of an edge if the distance of the point to that edge is
smaller than a threshold.
* Fixed both 3D and 2D code to utilize this. Possibly other places in
blender where this scaling is done will have to be adjusted.
* Changed vertex interpolation to use 2D interpolation, since it already
did projection on plane and 2d calculations are faster.
* Also added notifier on hard recalc when uvcalc_transfor_correction is
used. Results in instant feedback on UV editor when edge sliding.
