Oke right after i wrote the above i thought of the following case:
What if a user downloaded a wallpaper pack which uses the smart size
stuff that Matthias made? than the user would get the wallpaper that's
suitable for his size.
But what if the user wants (for whatever reason) a different size? i
don't see any option of doing that at the moment.

So i made a nice mockup of the Appearance Preferences -> Background
section and edited in the "Available sizes" option and some example
sizes with a radio button that indicates which one is gonna be used.
The place in that section is available to put it in.

Posted the same on the bugzilla page.
