GtkSelectionData can pass any array of bytes, it doesn't have to be a
string. The idea is that for a given target (such as text/plain),
the contents of the byte array are defined. So you can make up your
own target and define the byte array to contain whatever you want,
such as image data.

There's another problem with using set_data(), which is drags between
processes, though you may not always want to support that. (But, it
may be useful to know that the "user_data" field of a GdkWindow is the
widget that the window belongs to, if any.)
