FloodFill procedure
DECLARATION: FillFlood(X, Y : Integer; Border : Word)
PURPOSE: Fills a bounded region with the current fill pattern.
UNIT: The DOS unit
REMARKS: This fills an enclosed region on bitmap devices. (X,Y)
is a seed within the enclosed area to be filled. The area
will be flooded with the current fill pattern as set by
SetFillStyle or SetFillPattern. Be sure the seed point
is within the enclosed area or the outside will be filled.
NOTES: If an error occurs, GraphResult will return a
value of -7 (grNoFloodMem).
FloodFill stops after 2 blank lines have been
output. This can occur with a sparse fill pattern
and a small polygon.
Use FillPoly instead whenever possible to remain
compatible with future versions.
RESTRICTIONS: Not available when using the IBM-8514 graphics driver
