* If DOUBLE_BUFFER is commented out, don't bother to use extra pointer for the display buffer. * There's no need to wait for a buffer flip when starting up. It's fine to display the first (blank) frame indefinitely. * Don't bother using delay() while waiting for flips. All it does is bloat the code.
