	Having nothing much to do these days, I started working on svgalib
(and took my demo BGI stuff.....out) and got some interesting results.

First of all, I guess that running test programs as root (req for svgalib ?)
is very difficult. (I got about 3 crashes .....)

Then coming to the point (I haven't tried this in GNU). It must be a 
quite easy to produce XPM images from a screen image. Read an XPM image 
to get an idea of what I'm talking about. The ASCII format stuff should 
be good enough for most of the stuff. Then just xpmtoppm it and then
ppmto* ...... Most of this will work most of the time, I've tried it 
in my BGI stuff to get screenshots. But making an intelligent (sic)
color-to-char chooser will take some work. But for grayscale, or low-color
a static map will do.............

	vga_getgraphmem() ?

Hope you find this useful...........
