Idea for better skyboxes.
Edge already supports some kind of sprite based
skyboxes, but it could be better, if a ZDoom style
skybox could be used.
EXAMPLE:
http://www.zdoom.org/zdkb/skybox.html
Example how skybox can be used for cool things (video
from Action Doom):
Logged In: YES

Originator: NO
While there might be some cool uses for
this kind of skybox, I'm not really
interested enough to code it up.
