  I have a 386 with a VGA monitor with which I can display, using cshow,
256 color gif files with fairly accurate color reproduction.  I have
Turbo C professional, which comes with their "BGI" graphics library.
Looking thru the library documentation (and running some experiments)
it appears that, with their bgi VGA driver, I can only have 16 colors on
the screen at any one time, although I am able to change the color
pallette and access a broad range of colors.  Is this a limitation of
the VGA standard?  If so, how do programs like "cshow" work, that
accuratly display a much greater that 16 color image on the monitor?
