	Invalidate the image preview after the projection is
	completely constructed. Fixes bug #449141.

	* app/core/gimpmarshal.list: add VOID:BOOLEAN

	* app/core/gimpimage.[ch]: add boolean parameter
	invalidate_preview to the "flush" signal.

	* app/core/gimpprojection.[ch]: add boolean member
	invalidate_preview to the GimpProjection struct. Set it to TRUE if
	it was TRUE in the image's "flush" signal. When the projection is
	completely constructed after a flush, invalidate the image's
	preview.

	* app/display/gimpdisplay-handlers.c
	* app/widgets/gimpitemtreeview.c
	* app/widgets/gimpimagedock.c
	* app/widgets/gimpimageeditor.c: changed callback signatures
	accordingly.
