Don't underestimate the importance of the resolution info for the print
plugin. The following task may not be very professional, but it is
certainly something the average gimp user does frequently:
Scan in an image, retouch it, collage it, whatever, then print it.
When doing this with gimp-1.1.x all parts of the data stream support the
resolution information. The scanner plug-in uses it, the application gives
you the necessary infos in realsize units, you may even save and load your
image in between in a variety of formats. But when you choose to print the
image, that information carried along all the way is useless, since it is
simply ignored. We have added the image resolution in 1.1 only to make Gimp
better suited for printed graphics. CYMK support is still missing, but I
thought we'd at least manage to integrate the resolution info completely.
