Made the new "superknife" tool much stabler
then it was, though a few minor quirks remain.
Rather then the shortest-distance-in-graph method
I was using to rebuild the mesh post-knife I
reworked it to build a triangulation instead,
then merge the triangles into the right correct
faces.
Fixed join meshes, and an annoying modifier bug (making modifiers
not work in editmode). Also fixed a tesselation bug.
Also got edge slide to work right, yay! Dunno why I couldn't get
it working right before; took me twenty minutes to fix.
Implemented a new "super knife". Activate with k. Holding CTRL
will allow extended cutting ala old lines mode. Confirm with enter
and escape. You cannot cancel, btw, you can only confirm (and undo
later if you want). Hopefully I'll support undo within the tool soon.
* Supports cutting edges, into faces, etc. You can pretty much do whatever
you want. Will snap to vertices too.
* Note that if you cut into a face, it must be valid topologically when
you press enter to confirm.
* It's pretty and graphical :)
* You can only cut visible geometry.
* UVs/vcols are a little buggy still
Now, thou shalt all cease and desist all lack of motivation for
testing! No longer shall users put off testing until "it's cooler"!
:P
