bbox - prints out the bounding box of a rawppm or rawpbm image
[-l] [-r] [-h] [-V] [rawpbmfile]
reads a rawppm or rawpbm file and prints out the bounding box of the
image (as postscript comment and in postscript points, i.e. 1/72dpi) as well
as the high resolution bounding box. Input is read from standard input if no
filename is specified. Example output:
%%BoundingBox: 12 253 829 837
%%HiResBoundingBox: 12.500000 253.000000 828.500000 837.00000
has only very limited memory requirements as it reads the input line
by line and thus needs to store only one picture line in memory.

Special thanks goes to Michael Sharpe from UCSD who suggested a lot of
improvements for bbox to become more precise and robust, especially for small
