User definable UI viewport, to be able to restrict the UI into a viewport for all bitmap displays.

Flyspray: FS#8799

This will allow for pretty themes, for example those with nice glass effects on their backdrops (some might argue they're wasting screen space but it's upto them),
as well as allowing for future background WPS updates in the main UI.

Plugins are not converted yet, they simply use the full screen. Ideally, any plugin that does *not* want the UI viewport, should take care of that itself (i.e. plugins should normally use the UI viewport).
