19 15 in the virtual screen.

21 Copies part of a linear virtual screen in system memory at *virtual to
22 VGA 16 mode video memory. pitch is the logical width of the virtual
23 screen (in pixels (which are one byte large)), voffset is the address
24 offset into video memory, vpitch is the logical scanline width of the
25 screen. (w, h) is the size of the area to copy in pixels (width must
26 be multiple of 4).
