These Programs were written after a problem was highlighted by
Shlomo "Slo Mo" Hakim when trying to use CFSBmp to adapt the
default Variable-Transparency Propellor bitmaps for use in 
New Aircraft.

Problem :- Any changes to the bitmap would mess up the transparency
levels. Even though the palette contained the correct transparency
data the image appeared to be almost totally transparent on the
Aircraft model.

Reason :- After a lot of fiddling around I discovered that the fault
lay with the Paint Programs (in this case PSP but they all seem to
do it). Because these bitmaps contain just a few colours repeated
a lot of times through the palette (with steadily increasing transparency
levels) the Paint programs were trying to be helpful and remapping all 
the pixels to the first instance of the colour (of course they know
nothing about the transparency data so it just looks like there are a
lot of redundant colours in the palette)

Solution :- A bit of a hack but it is a very specialised problem.
2 Dos programs - one to create a new version of the image with the
palette crudely adjusted so that all the repeats of a given colour are
slightly different (and also to extract and save the original palette)
The other to restore the original palette after editing is complete.

Either extract the programs to a temporary folder or to somewhere in
your path (c:\windows\command\) then copy the original bitmap to the 
temporary folder, open a dos prompt, CD to the temporary folder and 
use the programs.....

StepPal <original-file> <new-file>

Run CFSBmp and load <new-file>
Do your editing in the usual way and save <new-file>

JoinPal <new-file> <final-file>

And you should end up with the successfully edited <Final-File> for
use in the Aircraft Model.
