It's a card game. It's not always refreshing, but if the three
computer handled players drop a card on the table, each time I need to
redraw everything. That's three times the blit of a  500x500 surface,
plus 8x4 cards maximum to copy to the surface with either
gdk_draw_pixbuf or gdk_draw_drawable.

nothing, it's just damn slow like click... wait....wait... ok now you
can move the card.

Again I must say it's just when playing through XDMCP, so that's kind
of unnatural situation, but again I want to know how to get a pixmap
from a file, and blit it to a drawing area pixmap without losing the
alpha and get a result similar to using gdk_draw_pixbuf
