Not at all. Trying to hide the details of SCREEN 12 behind a PSET-like abstraction is misguided. This operation is not what the hardware was designed to be good at! QB already provides you an optimised PSET, and an optimised LINE anyhow.
You can improve performance only by taking advantage of the special operations the hardware lets you do. I'm sure there are many opportunities for this in a windowing system, but finding them is no easy task. You need to read the specification and not only understand the features provided, but also appreciate how they can be useful.
So read all about it at the link I provided above. If you can't see the significance of certain hardware features let me know and I'll discuss.
