	* libgimpwidgets/gimpbutton.c (gimp_button_button_press): don't
	reset button->press_state on double clicks because
	GDK_2BUTTON_PRESS always arrive immediately after
	GDK_BUTTON_PRESS, so resetting the state causes the second click
	of a double click to be always interpreted as "clicked", not
	"extended-clicked", breaking e.g. adding of multiple layers by
	shift-clicking the layers dialog's "new" button. Phew, too much
	text for a one-liner bug fix, blah... Spotted by Jimmac.
	Cleaned up this antique file a bit.
