This unit looks most like what I want to do, except that the document
says that it should not be used together with the CRT unit, and that
doing so will result in very strange behaviour, possibly program
crashes.  Since the rest of my code uses the CRT unit (probably even
more than I use the direct video stuff), I am stuck.
