Hmm, Andy, you mean something like

if (ModeAvailable (GGI_Mode_1024x768x32_rgba))
	UseRenderer1024x32 ();

right? If not, the stuff below is irrelevant ;)

Such enums are very useful for finding out quickly if some *common* mode is
available. Of course the info is also available via the usual mode
description, such an enum is just much nicer to use than some
20-line-modeinfo-evaluator code ;)

It's common for games (mainly the 2d ones).
