Actually not. Most changes where done in gdb with "set var ...." ;)
let's do it from memory:
in winMWExtWMStartDrawing:
hdcNew = CreateCompatibleDC (pRLWinPriv->hdcScreen);
/* Describe shadow bitmap to be created */
pRLWinPriv->pbmihShadow->biWidth =
pRLWinPriv->pFrame->width;//pRLWinPriv->dwWidth;
pRLWinPriv->pbmihShadow->biHeight =
-pRLWinPriv->pFrame->height;//pRLWinPriv->dwHeight;
+ pRLWinPriv->pbmihShadow->biBitCount = 32;
/* Create a DI shadow bitmap with a bit pointer */
in winAdjust
- /* Query GDI for current display depth */
- dwBPP = GetDeviceCaps (hdc, BITSPIXEL);
+ /* Set the colordepth to 32 to please rootless code */
+ dwBPP = 32;
/* GDI cannot change the screen depth */
This is in no way safe and should be wrapped with a check for -internalwm but
safe for testing

I don't think so. We have way too much code anyway i think. 5 different
engines, to code
for handling windowed, pseudorootless and rootless code. If we find a safe way
to blit
from 32bit planes to 16bit planes then this will be quite useful in shadow GDI
mode
too. Sebastian Haby told me the 8bit pseudocolor patch he made has similar code
(blitting from a 8bit plane to 32/24/16 bit). I'll have to check the mail
archives
at home for this code
