Basically, for two reasons:

   1)	PostScript does not have any features that require reading the page
	framebuffer.  You can write to the framebuffer all you want, but you
	can't read it.  This is presumably for portability reasons.

   2)	Flood fill may give radically different results, depending on the
	resolution of the display device.  Regions which are closed on a
	low-res device, such as a display screen, may be open on higher
	resolution laser printers, etc.  Vice is also versa.
