UV transform correction tool
=============================
Commit work so far to have a stable backup where I
can diff against. The first part of the tool should be "finished" but
the code is disabled because i get crashes. I expect that when I resolve
the crashes I will at least have a working tool for uvs that do not
reside on stitches. Due to my misdesigning the tool I didn't account for
that but it will be added later, plus it will be a good test to see if
the principle works.
