oh, right. it's already on the table.

my main point was to raise the awareness that we have all this neat rectification code sitting in the corners which can be drawn upon when it comes to improving the new wxGUI tool. The more we can learn from gvSIG, QGIS, gdal_translate+gdalwarp, and old i.*points*, i.ortho.photo ideas+code while still in the design phase, the better the end result will be. Even if we don't implement it all at once.
