[GRASS-dev] updates to georectifier

I just committed an updated version of the georectifier.

Mainly, I’ve folded in vector georectifying, using v.transform. For this test version, I’m saving vector GCP points in a gcp file inside each vector folder. However, if we switch to a group model, this is easy to change.

I’ve cleaned up a few bugs and improved robusticity (I hope).

Zoom and pan still don’t work right, but resizing the window does.

Once we have a C module that can do the affine transformations for RMS error calculation, I’ll add that in.

As I write, something occurred to me. Does v.transform do an affine transformation on points? Is it different from the transformation done in the libraries used by i.rectify?
