Sorry to do this, folks, but I can't stand it any more.

  BitPlane  - a group of ordered bits corresponding one to one
              to pixels in some display.
  BitMap    - one or more BitPlanes which, together, determine
              the display characteristics of their associated
              pixels.
  ColorMap  - usually a table which maps BitMap pixel values
              to Palette colors.

And to confuse things even more, I've been calling the IBM CGA
style of mapping memory to pixels a "pixmap" for years!
