RELEASE 1.0.0
This is the first public release of the Trident 8900C SVGA library,
consisting of a modified version of Tommy Frendson's vgalib-1.0.tar.Z
package.
This has been tested on a number of Trident 8900C cards with 256k,
512k and 1M, without problems. If you do encounter any please let
me know, it's probably my fault and not Tommy's so don't bug him.

FEATURES
These are my additions to vgalib:

800x600x256 768x1024x16
1024x768x256
Functions: vga_drawellipse
vga_drawbox
-------------------------------------------------------------------
NOTES
o This library completely replaces vgalib so you should be able
to use it without changing any existing code that uses the
standard vga modes.
o I've included the README from the original vgalib since it's
still very much applicable. See README.vga
o For register level programming of the video card, the files
vga.doc and trident.doc in /pub/Linux/packages/X11/devel
at tsx-11.mit.edu are useful since they give valuable info
about register usage. They are not included here since they're
so easily available. Unfortunately they don't quite give all
the info that's required - see the file important.doc for
what's missing.
o I've probably done things inefficiently at places, and I don't
like some data structures I've used; my priority was getting
this running properly. I'll have to look at things closely at
some point.
