We used code from gnome-utils's gnome-screenshot/gnome-screenshot.c and
gnome-screenshot/screenshot-utils.c to add a capture capability to
java-gnome (we wanted window decorations and all, not just the GdkWindow
behind something; the drop shadows are nice too). We use this when
generating our API documentation, for example:
http://java-gnome.sourceforge.net/4.0/doc/api/org/gnome/gtk/AboutDialog.html

I certainly appreciate now that gathering a screenshot (window borders
and all) is very tricky and involves some voodoo mucking about with X. I
am quite thankful that such code existed to be reused.

Unfortunately it's not a library as yet, so we had to copy it manually.
Our import of it was a bit hack-and-slash, but our versions of the above
two files, as gnome_screenshot_capture.c and gnome_screenshot_utils.c,
can be found in ïa checkout of a java-gnome in the src/jni/ directory,
ie
