I mean the vnc protocol doesn't support 24bpp, so it couldn't help vnc
(I am aware that at the moment vnc is not using a DisplayAllocator, but
I guess it could in the future).

However I do agree that implementing 24bpp support in DisplayListeners
would be a better solution and if we did that I wouldn't object to
getting rid of DisplayAllocator.

Ideally we could also introduce a simple vnc protocol extension to
export 24bpp directly to clients.
