It depends what your question means. If your asking if you have to include it
for pixel fill load calculations then the answer is no, unless you redraw the
whole thing every frame. Work out how much you are drawing to the console each
frame and include that in your calculation. If this is some non custom gui area
with expose events etc then you'd want to do this a different way. Also you
don't want multiple threads rendering to the same pipe if it can be avoided.

For your other calculations (RM Memory, RM-DG bandwidth & DG dac bandwidth) you
must include the console unless you are using an ascii terminal of some sort.

A remote INDY might be a better way of running a console, even if you only use
it as an X server.
