INT 10 - VIDEO - GET FONT INFORMATION (EGA, MCGA, VGA)

	AX = 1130h
	BH = pointer specifier
	    00h INT 1Fh pointer
	    01h INT 43h pointer
	    02h ROM 8x14 character font pointer
	    03h ROM 8x8 double dot font pointer
	    04h ROM 8x8 double dot font (high 128 characters)
	    05h ROM alpha alternate (9 by 14) pointer (EGA,VGA)
	    06h ROM 8x16 font (MCGA, VGA)
	    07h ROM alternate 9x16 font (VGA only) (see #00021)
	    11h (UltraVision v2+) 8x20 font (VGA) or 8x19 font (autosync EGA)
	    12h (UltraVision v2+) 8x10 font (VGA) or 8x11 font (autosync EGA)
Return: ES:BP = specified pointer
	CX    = bytes/character of on-screen font (not the requested font!)
	DL    = highest character row on screen
Note:	for UltraVision v2+, the 9xN alternate fonts follow the corresponding
	  8xN font at ES:BP+256N
BUG:	the IBM EGA and some other EGA cards return in DL the number of rows on
	  screen rather than the highest row number (which is one less).
