Bingo.  Use the windows Rastport, and allocate a TmpRas and bitplane
and fill in the field and stuff.  Here is some simple sample code:

	struct Window		*MyWindow;
	struct TmpRas		 MyTmpRas;
	PLANEPTR		*MyPlane;

	/* ...assume window is now open and cant get bigger than WIDTH and
	HEIGHT */

	MyPlane	= AllocRaster(WIDTH, HEIGHT);
	if (!MyPlane) {
		/* ..barf and die..*/
	}
	InitTmpRas(&MyTmpRas, MyPlane, RASSIZE(WIDTH, HEIGHT));
	MyWindow->RPort->TmpRas = &MyTmpRas;

	/* ..when done clean up */
	MyWindow->RPort->TmpRas = NULL;
	FreeRaster(WIDTH, HEIGHT);

No problem.  Note that a TmpRas is only one bitplane, and that it must
be as big as the largest possible fill (ie: ScreenSize generally) just
in case the Flood() leaks you dont want it to scribble on memory.
