I'm not suspicious of SDL.

!!!   SURPRISE   !!!

I ask for 416x312
Hatari requests:
 SDL screen request: 416 x 276 @ 0 (windowed)
 SDL screen granted: 416 x 276 @ 32
I say WRONG and WRONG
Monitor says (on screen independently):
 832x624
I get a full screen at 416x312 (see xrandr below)

xrandr output looks very reasonable. Resolutions below
may be undocumented for the monitor, or maybe my old
R100 [Radeon 7200 / All-In-Wonder does something.
