1. RE: double buffering
David,
Double buffering, in a nutshell, is the process of updating a screen
buffer while another is being displayed. In DOS, you might display one
graphics page while updating another graphics page in memory. When you
are done updating, you blast the entire updated screen buffer to the
display and the process starts over.
In windows using Win32Lib, you would typically use a Pixmap as a buffer
and copyBlt that Pixmap to the Window when the update is done. The
result is faster, smoother animation because updating memory (your
buffer) is typically much faster than updating the screen.
