A VESA hi-color and truecolor toolkit. An earlier version was posted on

PKZIP v204G archive:
This is a update to VESA24.ZIP . The VGAFILL() function is fixed. the
fix is documented in the VGA24.ASM file.
The archive VESA24_3.ZIP contains ten files. VHEADER.H is the VESA 
information structs necessary for properly accessing your video card 
with VESA in rom or with a VESA TSR. The file VGA24_2.ASM is the actual 
pixel handling toolkit. It was written by Randy Buckland (good work)
(Randy_Buckland@ncsu.edu) and modified by myself Don Lewis 
(djlewis@ualr.edu). Randy's original code, while well written to perform 
it's task, overlooked hi-color and truecolor VESA modes. Also it only 
worked on certain video cards like TSENG and TRIDENT in only 256 colors 
and only 640x480 resolution (mode 0x101h) VESA. VGA13.CPP gives examples 
on utilizing the graphics library in VGA24_2.ASM. I wrote it and tried to 
debug it while keeping it as simple as possible ( too simple for most of 
you 'C' folks out there ) and documented adequately ( I hope ).
Vesainf.cpp is an example on how to get vesa card and mode information.
	The modifications I have made ( I hope ) fix the .asm file such 
that it now should work on any VESA compliant video card. I hope it gets 
tested on many video cards with VESA in rom and by using TSR's so I can 
know of my success or failure. I added 15bit, 16bit and 24bit color support 
for several but not all original functions. VGAFILL(), vgapoint_rgb() and 
vgaline_rgb() are the first.  I would appreaciate help in refining the code 
as there is still much room. I have talked to Randy and he approved the 
modification and passing around of the original source code. So I have done 
just that. I have heard a lot of requests on comp.graphics and 
comp.pc.hardware from individuals interested in any VESA code they could get. 
I was one of them. This source along with a good VESA functions guide should 
prove most helpful to all interested parties.
