Reads a portable graymap as input. Produces a Lisp Machine bitmap as
output.
This is the file format read by the tv:read-bit-array-file function on TI
Explorer and Symbolics lisp machines.
Given a pgm (instead of a pbm) a multi-plane image will be output. This
is probably not useful unless you have a color lisp machine.
Multi-plane bitmaps on lisp machines are color; but the lispm image file
format does not include a color map, so we must treat it as a graymap
instead. This is unfortunate.

Output width is always rounded up to the nearest multiple of 32; this
might not always be what you want, but it probably is (arrays which are
not modulo 32 cannot be passed to the Lispm BITBLT function, and thus
cannot easilly be displayed on the screen).
No color.
