Flood -- Flood rastport like areafill.
error = Flood( rp, mode, x, y)
d0 a1 d2 d0 d1
BOOL Flood(struct RastPort *, ULONG, SHORT, SHORT);
Search the BitMap starting at (x,y).
Fill all adjacent pixels if they are:
Mode 0: not the same color as AOLPen
Mode 1: the same color as the pixel at (x,y)
When actually doing the fill use the modes that apply to
standard areafill routine such as drawmodes and patterns.
rp - pointer to RastPort
(x,y) - coordinate in BitMap to start the flood fill at.
mode - 0 fill all adjacent pixels searching for border.
1 fill all adjacent pixels that have same pen number
as the one at (x,y).
In order to use Flood, the destination RastPort must
have a valid TmpRas raster whose size is as large as
that of the RastPort.
