	* app/gdisplay.c app/gdisplay.h app/gimage_cmds.c:

	An image's projection is now copy-on-write duplicated
	upon duplication of the image.  This should save some
	time and memory for 'duplicate'.

	This needed a new function which is prototyped in gdisplay.h:
	gdisplays_finish_draw() which completes all outstanding
	idlerendered-projections (we don't want to c-o-w an
	incomplete projection).

	* app/interface.c: #include "dialog_handler.h"
