[Gnome-print] gnome_print_rgbaimage bug

[Thomas Hudson <thudson tomy net>]

I'm trying to print a bitmap with an alpha channel, but it
seems gnome_print_rgbaimage, using the postscript driver
outputs all white (0xffffff). I noticed from the code, that
for print classes not supporting rgbaimage, you blend to
white, but in the case of the postscript driver it doesn't
seem to be taking this route.

Is this code implemented?

Thanks,
Tomy
