We recently built a video digitizer that furnishes us with 6 bits of intensity
(somewhat linearly).  I am interested in displaying its output on a
black & white display that has only two levels of intensity (on or off),
but 16 times the resolution (4x both V and H).

I've made a simple halftone routine that just interpolates scattered points, 
but I'm dissatisfied with the resulting image.  I think something more
sophisticated might look better.

Pointers to algorithms (especially those that adapt to varying minimum
and maximum intensities) would be greatly appreciated.
