Comment 4 for bug 679162

In general the hugin control point editor can be improved.

- Allow rotating of the images through the gui (not only through running an optimizer step, and then having the gui detect which side it thinks is up.

- Allow non-90 degree rotations to line things up. (I've been known to pick the wrong control point when SIFT didn't work either).

- Allow different scales. Just a linear scale will do. (in the case above the 12 degree shots are 1/30th of the 360 degree pano.) (The example above is a bit extreme, but I really want to be able to make those panos eventually).
