it does - for 16-colour support + other tricks :)
I would -really- like to add some more support too for things like
paged-mode and svgalib acceleration....  I have -never- liked libvgagl...
(found it highly inefficient in many spots and easier just to rewrite.
AFAIK libGGI could handle it :)

Easily enough done.  Had them working in my own code - now to just get
around to it :)
[w' support for any 1bpp/4bpp mode svgalib supports.  There's some
weirdness there that involves a wee bit of hacking around but the demos
for svgalib show how to fix :]

Turns out to be two causes:
	1. I've got "linear" turned on but my card refuses linear mode
		(so GGI mixed up....)
	2. I've got svgalib-1.2.11.... *grin*

G'day, eh? :)
