Well, all the information that belongs to a drawable and/or image
object should be object properties. This would be width, height, mode
(RGB/Gray/Indexed), unit ... Having this information accessible (at
least readable) via the GObject property system will make it a lot
easier to write a more or less generic property dialog.

A must-read for every core GIMP hacker:

The GIMP source code is a good example also. Check the app/config
directory for a couple of classes that basically do no nothing but
storing information as object properties.
