	Uses 'vobj' of width 'vwid' as the screen, 'fg' as the color, 'vb' as
	the bank, 'pitch' as the vertical pitch, and 'ml' as the pattern.

	If 'vb' EQ -1,  the bank is not set.  The color in 'fg' will be taken
	from the lower 4 bits.

	The list 'ml' points at pairs of counts and characters.  The last count
	is -1,  and the list terminates with a null pointer.
