	* libgimpwidgets/Makefile.am
	* libgimpwidgets/gimpbutton.[ch]: new widget derived from
	GtkButton.  It adds an "extended_clicked" signal which is emitted
	instead of "clicked" if a modifier was pressed.

	* libgimpwidgets/gimpchainbutton.[ch]
	* libgimpwidgets/gimppixmap.[ch]: removed the opaque typedefs.

	* libgimpwidgets/gimpwidgets.h
	* libgimpwidgets/gimpwidgetstypes.h: and added them here. Added
	GimpButton.

	* app/widgets/gimpdrawablelistview.c: use GimpButtons for "Raise"
	and "Lower" and raise/lower to top/bottom on shift-click.
