                INT 10,C - Write Graphics Pixel at Coordinate


       AH = 0C
       AL = color value (XOR'ED with current pixel if bit 7=1)
       BH = page number, see VIDEO PAGES
       CX = column number (zero based)
       DX = row number (zero based)


       returns nothing


       - if bit 7 is 1, color specified is XOR'ed with current pixel
       - page number in BH ignored for 320x200 4 color graphics mode
       - this function is known to destroy AX and possibly SI and DI on
         on some PS/2 VGA systems
