Save to image broken

[king]

As it turns out, the save to image feature does not work with the new zoom feature when changing the size of the image to save to be different from the OpenGL canvas size. This happens because the zoom factor is base pairs per pixel. If you increase the size of the image to be twice the size of the OpenGL canvas, you have to decress the base pairs per pixel to be half of the OpenGL canvas zoom factor in order to get an enlarged image (rather than a horizontally squashed image).

It's also broken in the sense that it doesn't save right now either. (perhaps this should be a seperate ticket, but the summary is too appropriate...)
