I haven`t tried it but, I`m reliably informed that, you do not have to wait
for the vertical blank when using triple buffering. IE. you don`t have to do
WaitTOF() in your code at all. I wonder if in practice what happens when you
call ChangeScreenBuffer() is it performs the WaitTOF() and the swap
asynchronously to your proccess. The autodoc for ChangeScreenBuffer() seems
to suggest this might be the case:
"The previously-installed BitMap is available for re-use upon receiving a
signal from graphics.library."
Who knows?
