- Reads a Lisp Machine bitmap as input. Produces a portable graymap as
- output.
-
- This is the file format written by the tv:write-bit-array-file function
- on TI Explorer and Symbolics lisp machines.
-
- 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.

- The Lispm bitmap file format is a bit quirky; Usually the image in the
- file has its width rounded up to the next higher multiple of 32, but not
- always. If the width is not a multiple of 32, we don't deal with it
- properly, but because of the Lispm microcode, such arrays are probably
- not image data anyway.
-
- Also, the lispm code for saving bitmaps has a bug, in that if you are
- writing a bitmap which is not mod32 across, the file may be up to 7 bits
- too short! They round down instead of up, and we don't handle this bug
- gracefully.
-
- No color.
