────────────────────────────────────────────────────────────────────────────
The setfillmask subroutine sets the current fill mask, which
determines the fill pattern. The mask is an 8-by-8 array of bits,
in which each bit represents a pixel. A 1 bit sets the
corresponding pixel to the current color, while a 0 bit leaves the
pixel unchanged. The mask is repeated over the entire fill area.
If no fill mask is set (<mask> is all zeros──the default), only the
current color is used in fill operations.
Return Value
None.
