  Image based on a 1-bit bitmap from memory. This matches the very
  first type of image provided with X10 in 1980 or so, and unfortunately
  the only one that draws with any efficiency even today...

  Every pixel is either black opaque or black transparent, determined
  by the 1 and 0 bits in the provided bitmap. Perhaps I should add a
  single color as another argument? You can also call the draw(x,y)
  method which will use the current color.

    Because bitmaps are only 1 channel, it makes sense to draw them
    with a solid and settable color. This function does so. It will
    draw them with the upper-left corner at the given position.

    Note this has the same name as a virtual function on Symbol, but
    it is not an override of that function.
