Bug fix for djgpp version of POV 2.0
This file replaces the original ibm.c file.
It fixes the bug with video autodetection and vesa modes.
It also adds support for the Paradise true color and full color modes
(options -d9T and -d9H).

/* Original IBM VGA "colour" output routines for MS/DOS by Aaron A. Collins.
This will deliver approximate colorings using HSV values for the selection.
The palette map is divided into 4 parts - upper and lower half generated
with full and half "value" (intensity), respectively. These halves are
further halved by full and half saturation values of each range (pastels).
There are three constant colors, black, white, and grey. They are used
when the saturation is low enough that the hue becomes undefined, and which
one is selected is based on a simple range map of "value". Usage of the
palette is accomplished by converting the requested color RGB into an HSV
value. If the saturation is too low (< .25) then black, white or grey is
selected. If there is enough saturation to consider looking at the hue,
then the hue range of 1-63 is scaled into one of the 4 palette quadrants
based on its "value" and "saturation" characteristics.
Further SVGA, MVGA mods by Aaron A. Collins:
SVGA, MVGA assembler routines originally by John Bridges.
VESA assembler routines from FRACTINT, by The Stone Soup Group
AT&T VDC600 SVGA mods to DKB Trace 2.01 module IBM.C by John Gooding
This file now represents the collective wisdom of the VGAKIT34 package,
with support for all of the SVGA types known to mankind. Seriously,
VGAKIT34 is an excellent technical reference for IBM programmers wishing
to do any sort of SVGA video access, and it encompasses nearly all of the
SVGA adapters in use today. It was written by John Bridges, a.k.a.
CIS:73307,606, GENIE:J.BRIDGES. It was originally coded in IBM 80x86
assembler, and since DKBTrace is a completely "C"-based package, I have
converted John's assembler routines all into "C". These may be a tad bit
slower, but they should be compatible across a wide variety of 80x86/(S)VGA
machines. Note if you have a regular cheapo VGA card like myself, included
is "MODE13x" or MVGA (modified VGA) mode (some call it "tweaked", but I
call it "Simulated SVGA"), which gives 360x480 on any reasonably register-
compatible plain vanilla VGA card. This mode gives a good simulated 640 by
480 screen resolution. I did not implement all the neat hi-res modes of
all the various SVGA adapters, if you select a trace size bigger than the
program and/or card can handle (most likely 640x480), it is dynamically
scaled to fit the available resolution, so you'll be able to see a rough
approximation of an 800x600 trace even on any el-cheapo VGA card at 320x200
resolution. The VESA VGA mode was freely adapted from FRACTINT, whose GIF
reading routines we are already using in DKBTrace. I hope my conversion
of it works properly.
There is still a reported problem with the EVEREX autodetect returning
TRIDENT. In fact EVEREX uses a TRIDENT chip set, but apparently there
is some difference in operation. There are cryptic diagnostic messages
such as T0000, etc. printed as a result of the autodetection routines
to help track down why the error is happening. If you are experiencing
problems with EVEREX or TRIDENT, make note of the letter-4 digit code you
are given. There is now an autodetect for VDC600 that I hope will work
universally. A similar problem as the EVEREX exists, in that the VDC600
is detected as a PARADISE because it uses the PARADISE chip set. I am now
looking for what I believe to be the model number in the BIOS ROM of the
VDC600 to differentiate between the two. I hope this works with all
VDC600's, as I only had one example to work from. Please send all bug
reports to Aaron Collins at the "You Can Call Me RAY" BBS, the number is
in the authors.txt document.

Additional support for VESA and Tseng Labs 256 and 32768 color modes by
Charles Marslett (CIS: 75300,1636). Resolution is selected to be the
lowest possible and still fit the image entirely on the screen. 4/28/91
ATI VGA Wonder XL Support for 32,768 color mode and all other SVGA modes
by Randy Antler. Also image centering, outline box, and forces SVGA mode
for small images. Minor bug fixes and cleanups as well. 9/11/91
Combined IBMPRO.C and IBM.C into 1 file.
B.Pulver 10/20/91
Corrected defects in the centering and high color support for VESA modes
(particularly necessary for the newer 24-bit color cards and S3 based
Windows accellerator cards) -- Charles Marslett, 12/8/91 to 4/25/92.
Extended Doug's dithering code to other high color modes and eliminated
a bad validity check in the 24-bit code high color cards. Had to add
an "#include <float.h>" to ibmconf.h for the WATCOM C compilers with the
patchlevel C include files -- Charles Marslett, 10/4/92.
Added support for Diamond Speedstar 24X. Uses a modified copy of some
of the Paradise code. There is no AutoDetect functionality for this
card, though. Note that a couple of pixels (about 14), namely those
that straddle bank boundaries will be displayed incorrectly.
-- Lutz Kretzschmar, 10/30/92
Fixed (obvious) bug for displaying images larger than screen
resolutions. Strange no-one caught it, it didn't work!. The line coord
cache is set to the max value by the box() function. Added code to
reset the values inside box().
Added bank switch checking inside pixels for truecolor modes.
Added HiColor display in 640x480 and 800x600 resolutions for Diamond
SpeedStar 24X. -- Lutz Kretzschmar, 11/05/92
Added TARGA+ display adapter support and reworked find_go32() to make
the VESA and TARGA routines work properly with DJ's port of IBMGCC
- Aaron A. Collins, 2/2/93.
Completed Intel Code Builder code for VESA 1.2 support. - B.Pulver 2/15/93
Added: Set palette to P_332 if Hi/True color VESA init fails.
Doubled dithering matrixes to support 2048Xxxxx images.
Added code to disable dithering @ rez over 2048Xxxxx.
Added message warning user of failure if no_valid_mode is called
during VESA initialization attempt. - B.Pulver 5/13/93
Found consistency bug in previously fixed find_go32(), so this too
has been fixed. Found DJGCC's setvbuf() was blowing up the VESA/TARGA
"answer" area (in low real mode accessable mem) after a disk write, so
the setvbuf() function has been dummied up in this file to do nothing.
Added some DEBUG_VIDEO diagnostics for figuring out problems running a
TARGA+ display on the Intel Code Builder. - Aaron A. Collins, 8/2/1993
Updated Watcom VESA support for DPMI. -- Carl Peterson 1/94
Added support for Paradise true color cards (option PARADISE) :
FULL color (32000+) and true color modes. The code for full color modes
is exactly the same as the one for the Diamond 24X, but not the code for
the true color mode. Did not add support for 800x600 and 1024x768 modes
with 256 colors, please use the VESA option for these modes.
Fixed bug with autodetect video modes and vesa modes with DJGCC
(deleted find_go32() and used the _go32_dpmi_simulate_dos_int() with
_go32_linear_address_of_transfer_buffer). Emmanuel Anne, 30/8/1994.
