	* app/devices.h
	* app/disp_callbacks.c
	* app/interface.c: applied a patch from <David.Odin@bigfoot.com> that
	changes some function prototype to return gboolean instead of gint.

	* app/tools/gimpblendtool.c: pixel_regions_register() and
	pixel_regions_process() return a gpointer, not (gpointer *).
