Patch #1013937 "OSystem layer with bigger resolution". Now you will always

get at least 640x400 window. And finally we have means of implementing
nice looking GUI.

Also updated all backends. If your backend has ability to run with 640x400 or
640x480 resolution then read patch tracker item to find out details. Other
port maintainers shouldn't worry, as this patch doesn't affect them, they
still get their 320x200.
