Well, no server changes are needed just to implement 32 bits per pixel.
There are rather simple changes needed in the file
dlls/winex11.drv/mouse.c in create_cursor(), and the places that need to
be changed are cleverly marked by "switch (ptr->bBitsPerPixel)" ;)
I tried installing Google Sketchup, but could not get that to install.
That said, it looks like 32 bit pixels use 8 bits each of RGB, plus an
extra 8 bits of "alpha" (which apparently controls transparency). So
probably you could duplicate the 24 bit case, read out the extra 8 bits
and just throw them away for now. Standard X cursors don't support
