Note that I prefer to have limitations on size and position. Do you really want
to code the `generic' case for bitplanes? Limiting sizes and positions to
multiple of 8 helps a lot here to keep the code simple. And you don't really
need more for a text console.

For modern cards with packed pixels this doesn't matter that much, especially
in a mode with 32 bits per pixel :-)

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
