Re: [Dev-C++] some more to Graphics

Hi,
 
Someone asked about page flipping in SVGA modes.
This can be done by playing around with the view position. The screen is
a 640x480 viewport into 640xwhatever screen, which can be
hardware-scrolled vertically. You can draw to 0-480 while showing
480-960 and vice versa for example.
The view location is a BIOS call. I don't remember it by heart but look
at VESA2.0 specs and you'll find it easily.
