Ability for exclusive fullscreen and select monitor.

[Cyrus-Harding]

Last time I used ZSNES, the old version when it could still be compiled on modern hardware, going into fullscreen would change the resolution on the monitor.

When I go into fullscreen it now doesn't, it stretches nicely, and looks very nice on LCDs. The thing is, though, I've got a CRT which I would love to run the native resolution on, but this doesn't work. It's also a pain to make ZSNES run in fullscreen on it, as it's the secondary monitor. It would be nice to have a monitor selection.

Thank you.

Compiling ZSNES with libsdl 1.2 and not 2.0-compat fixes this. However the resolution changes are permanent (even after closing ZSNES) which is not really intended. I will try to see if I can implement some form of monitor selection and proper fullscreen resizing.
