well unlike dos or windows ... you can't manipulate bits directly ... the
image (pixmap) is stored on the server ... and the only way to get to it is 
though X calls ... if you did operations in the client space you need to 
get them into server space (read slow) ... what you need is to store
everything as pixmaps and use gdk_draw_pixmap
