Description
(Someone asked about this on the user list a week or so ago. I thought there was already a ticket, but if so, I can't find it)
It would be useful to implement raster edge detection to allow for snapping to raster layers, both when digitizing and when georeferencing.
The AutoGCP plugin must be using edge detection, so maybe some of the work is already done. Or maybe some code could be borrowed code from another program such as Hugin. (Hugin is a panorama maker that allows snapping when manually creating control points. But Hugin uses wxWidgets.)

No. Reading the message again I think I misunderstood.
They actually wanted to be able to make the corners of a the raster image snap to a vector grid http://lists.osgeo.org/pipermail/qgis-user/2010-December/010634.html
