Chnages between DOS and 3DO graphics.
[Unless stated otherwise, UQM does things 3DO way]

----------------------------------------------------------------------
Melee
----------------------------------------------------------------------
1. Minor ship small icon changes
Icon offset horz by 1 pixel: VUX, ZoqFot, Melnorme, Supox
Facelifted: Utwig

2. Ship/weapon rendering changes
*Yehat*
On DOS, Yehat shield was a set of separate shield-only images which
were composited with the ship; on 3DO, the shield images already include
the ship.
*Umgah*
On DOS, Umgah cone was a composite of a cone mask + spritz images;
on 3DO, cone images multiplied 3x and are already a combination of
cone + spritz.
*Blackurq* [Kohr-Ah]
Ship images were regenerated for 3DO with a light source
at a different position (so the angle is diff). This improved the overall look
of the ship, especially frame 14, which was simply ugly on DOS.
And, of course, the FRIED is blue on 3DO and was yellow on DOS.
*Chenjesu*
Not really a change, med.14 frame has bad transparency info on DOS.
*Utwig*
DOS has apparently derelict ship frames (16-18).
HYPOTHESIS: ship special was originally intended to be some entirely
different.
*Sa-Matra*
The captain portrait is bigger in UQM (same size on DOS and 3DO).

4. Misc
lbm/stars has an extra frame (2) in 3DO, afaik, it is not used.

5. Planet images
On DOS, planet images were paletted, and there were 14 topographical types
(2 were identical) with ~60 palettes; on 3DO, images are truecolor (except
for Shielded planet), and the 2 identical topographies have been fixed (so
they are different now).

----------------------------------------------------------------------
Inter-planetary (IP)
----------------------------------------------------------------------
1. Planets
On DOS, IP planets were all pre-generated (all phases, colors, sizes);
On 3DO, planet phases and size are pre-generated and rendered using colormaps
that define planet color.

2. Many changes in Planet Rotation (scan view)

3. Suns
On DOS, suns have different colors; on 3DO, they are all yellow; UQM has
been patched to render suns in different colors like DOS.

----------------------------------------------------------------------
Misc
----------------------------------------------------------------------
1. SIS engine color was green-yellow on DOS and is red on 3DO
