Campbell Barton 5fa576a89f UV Unwrap (lscm, project from view, cube etc) now default to correcting for the active images aspect ratio.
This is now default but can be disabled in the UV Calculation panel. At the moment its called "Image Aspect" but another name could be better.

-------------------

- vertices are implicitly created
- in construct_end the mesh will be split up according to the seams
- the resulting charts must be:
- manifold, connected, open (at least one boundary loop)
- output will be written to the uv pointers
