I recommend we use gdk-pixbuf as a model. Basically, we do the simple
formats (ie. BMP) ourselves and link to libs for the hard ones (ie. JPEG).
libjpeg, libungif, libtiff, etc, should be pretty portable. The ungif
source might small enough to just copy, too...
It's not much code and it avoids large lib dependencies.
However, one other suggestion: can we make these image importers
subclassable to platform specific implementations? For instance, with the
gnome version, I'm certain we'd like to just swap this code out for the
actual gdk-pixbuf implementation. I imagine there are similar services on
other platforms. We don't have to do it right away, of course, but I'd
like the ability to be there for later extension.
