I'm having a problem figuring out how the Flood() function works.  I've
been able to get flood mode #0 (flood to the outline color) to work, but
it's incredibly slow (even on my 3000), and not really what I want anyway.
Mode #1 (flood the block of color at the given coordinates), on the other
hand, looks like it will fit the bill, but I haven't been able to get it to
work.  Here's a code sample that illustrates what I'm trying to do
(ignoring the fact that this could be done with RectFill or AreaInfo):

#include <exec/types.h>
#include <intuition/intuition.h>

struct NewWindow NW =
{0,0,300,200,-1,-1,NULL,WINDOWDRAG,NULL,NULL,"Window",NULL,NULL,
0,0,640,400,WBENCHSCREEN};

struct Library *IntuitionBase,*GfxBase;
struct Window *wdw;
#define Rp wdw->RPort

main()
{
	 /*Open libraries*/
   IntuitionBase=(struct Library *)OpenLibrary("intuition.library",0L);
   GfxBase=(struct Library *)OpenLibrary("graphics.library",0L);

   wdw=(struct Window *)OpenWindow(&NW); /*Open window*/
   if(wdw==NULL)  /*Exit if not opened*/
      exit(1000);

   SetDrMd(Rp,JAM1); /*Set drawing mode and pen*/
   SetAPen(Rp,1);

   Move(Rp,15,20);   /*Create a box from (15,20) to (100,100)*/
   Draw(Rp,15,100);
   Draw(Rp,100,100);
   Draw(Rp,100,20);
   Draw(Rp,15,20);
   Flood(wdw->RPort,1,30,30); /*And fill it (but it doesn't work!)*/

   Delay(100);       /*Pause for a bit...*/

   CloseWindow(wdw);    /*Cleanup and exit*/
   exit(0);
}

I'd appreciate it if someone could point out what I'm missing.  Thanks.
