Description
While investigating #3337 I have discovered that the conversion of IGEOLO corners into a geotransform and then back into corners (projected out a half pixel) can cause significant errors if the corners are not exactly convertable to a geotransform. This is a problem introduced some time ago (r7382).
Upon further review it is not specifically an issue with #3337 since that file later overrides the corner coordinates from the RPF header; however, it does still seem it could affect other files.

In r18635 I have modified the code, essentially backing out r7382, and instead tracking whether the corner coordinates are center of pixel or edge of pixel.
As I haven't actually encountered a file misinterpreted by this issue, I am not inclined to back port the change.
