KImageShop is like every KOffice application an OpenParts application. OpenPart
are a layer on top of KOM handling the GUI stuff, while KOM implements
basic things like signals and events.

Yes, we had the idea of using KOM for plugins and filters. But CORBA is to slow
to transfer large amounts of data (like image data). So we reconsidered and IMO
we should simply define a normal plugin/filter interface and put them in shared
libs. But I still think we should use KOM to make things like the a gradient
editor available for other apps.

You are right, a plugin interface based on KOM would require KOM interfaces for
brushes, channels, layers, etc...

Hm, you are right, we should put custom KIS widgets and classes plugins may
want to use in a shared lib later. But let's implement a plugin system first.
