 +==== Description of getactivepage ==== 
 +<code c>
 +The getactivepage function is available in the winbgim implementation of
 +BGI graphics. getactivepage gets the page number of the currently active
 +page (where drawing takes place).
 +The active graphics page might not be the one you see onscreen, depending
 +on how many graphics pages are available on your system.
 +The original winbgi was designed to support up to 16 pages, but I have
 +only used pages 1 and 2 myself. NOTE: Using page number 0 might mess up
 +the colors. I use pages 1-2 for double buffering.
