Cygwin/X developement: -EMULATEPSEUDO

["Sebastian Haby" <sebastian dot haby at mil dot se>]

Hey!

I started to try out Cygwin/X to remotely use a Solaris app, however, the 
app uses 8bpp Pseudocolor visual which is only
supported in Cygwin/X when running the windows desktop in 8bpp aswell or 
fullscreen, ie. the app works just fine in these two cases.
However I can't use any of these options and therefor need to get the 
-emulatepseudo option to work.
I've got the option to compile into XWin but my problem still remains, 
menys and certain areas are fine but parts that are suppose to be white 
and have lines, rectangles etc.. drawn into them are black.
>From what I've worked out from looking at the sources the -emulatepseudo 
option does setup a 8bpp pseudocolor visual aswell as a normal
truecolor visual, but how can i verify that my app draws into the 
pseudocolor visual, does the app supply the correct visual ID to my 
Xserver?
I've also tried telling XWin to use PseudoColor visual as default visual 
id by supplying the -cc option. (-cc 0x27 or -cc 27) but it is ignored.

One thing i haven't figured out yet is with ShadowGDI, it allocates one 
screen and one shadow bitmap and blits changes between the shadow and 
screen bitmap, also I assume
that the truecolor visual somehow points to the shadow bitmap, but where 
does the pseudocolor visual point to? shadow bitmap aswell? why not 
allocate another 8bpp bitmap DIB(is this possible?) or in system ram? and 
then do some color conversion and blit between that and screen bitmap? 
I've got lots of payed time to work on this problem so any pointers / tips 
from other developers where to start / where the problems are etc...
are greatly appreciated.
