Hmmm, drops into GTK+ from KColorChooser don't seem to work.

(testgtk:8556): Gtk-WARNING **: Received invalid color data
 
(gdb) p data.format
$14 = 8
(gdb) p data.length
$14 = 8

The contents look like little-endian 16 bit data, so I wonder
KColorChooser can DND to itself across endian properly?

$ rpm -q kdelibs
kdelibs-3.1-10

Bug still looks to be there in CVS, though it's not clear to me
how to make QDragSource advertise a different format.
(The format says what the units of the data are, and thus
how byte swapping works.)

We could make GTK+ accept format-8 drags as well, but there 
would have to be a definition of what endian to expect.
And it's certainly a bit ugly... :-)
