I had earlier added support for limiting any resolution request to
desktop size.

Attached is a patch to make fullscreen mode always use the current desktop
resolution for Falcon & TT resolutions[1].  It's enabled by giving Hatari
a "--desktop" command line option.

Does it do what you were looking after?

[1] ST & STE mode screen handling doesn't have scaling with arbitrary
     integer factor, just doubling, so doing that for those too wouldn't
     look very nice.  I don't thing it's a problem though as ST/STE demos
     don't by themselves cause Hatari resolution changes like Falcon demos
     do.


(When I had it enabled also for non-fullscreen mode and did couple of
fullscreen switches, SDL somehow managed to mess up my Linux desktop so
badly that I had to kill the whole session to see anything else than black. 
Doing it just for fullscreen would seem to work fine though.)

PS. I'm now using an LCD monitor too and they indeed are bloody slow
at changing resolutions, so this started to be a more interesting issue...
