My bad - I was thinking of the WinStr (or whatever they're called) routines -
they can do clipped text in a memory area of your choice if you PortSet()
correctly.
In your case though - if you draw every character every time then there will be
more work the more characters are visible on-screen. Every character you draw
will be clipped, but the ones outside of the screen will be clipped _faster_.
