Hi Paul, I realise that Allegro is pretty darned quick at what it
does, blows the socks off anything I could write, what I really wanted
to know was was I overlooking some set of functions or something that
would enable me to do what I wanted to do a little quicker, there are
always quicker ways to achieve a task depending on what lengths you
are prepared to go to, otherwise people like ID would be using
 Allegro. 
For instance Allegro might have supported some function to program
which part of the VRAM the DAC read from, avoiding the need for
coppying buffers around.
	I am new to allegro and wanted to make sure I wans't missing
some fundamental thing.
