   Although the Flood code fragment in the RK manual does not show
a TmpRas allocation, I believe you do need a TmpRas to use Flood.

  Declare or allocate a TmpRas structure.
  Use AllocRaster to allocate a TmpRas raster the size of one bit-plane
  Use InitTmpRas to initialize your TmpRas structure.
  Link the TmpRas structure to the RastPort you wnat to Flood() in
    by putting the address of your initialized TmpRas structure
    in yourRastPort->TmpRas.
 
  (now try Flood)

  And remember to FreeRaster the extra bit-plane you allocated in
  your program cleanup.
