since you are talking about 24bit packed pixels it doesn't make much
sense to speak about byte order here. GdkRGB simply expects a RGB
buffer, independent of the host byte order.

you might get away with tricking GdkRGB to believe that the byteorder
of your screen is different than it really is by fiddling with the
private members of the GdkVisual but don't tell anyone that I even
mentioned that this might work...
