Widescreen Aspect ratio and more

BlitzMax Forums/BlitzMax Programming/Widescreen Aspect ratio and more

I'm interested in supporting widescreen on my game, but I want to make windowed mode proper widescreen aspect ratio, but I want fullscreen under 4:3 to have little borders at the top and bottom.

This means it's a widescreen-native game, and feels kinda cinematic.

What do I need to do in order to support both? All wisdom accepted and gratefully appreciated :)
