I'm trying to hack the video settings menu now to change the space for Windowed Modes into three settings:
BPP: Output of the image depth. This driver only does 32bpp, would be nice to have 16bpp and 8bpp back in there. Would help Windows9x support
Windowed: Instead of just 3 exclusively windowed modes, this would allow any of the fullscreen resolutions below to go into windowed mode.
Aspect: Filter the selections of modes to show only modes for the selected aspect.
So far only the Windowed thing is implemented.
