Technically it is a gray map - you can take the output of '-o pgm'
and view it with xv/gimp/whatever and it will display as the luma

Actually fairly useful when looking for shifts/misalignment.

Short is good? Didn't feel like typing out the extra characters.
Anyone using it will (or should) know what they're doing and the source
has a big block of comments at the top detailing the intended use and
a description of the data layout (P5 "raw"), etc.
