Reads raw RGB bytes as input. Produces a portable pixmap as output. The
input file is just RGB bytes. You have to specify the width and height
on the command line, since the program obviously can't get them from the
file. The maxval is assumed to be 255. If the resulting image is upside
down, run it through pppnnnmmmfffllliiippp ---tttbbb ...

---hhheeeaaadddeeerrrssskkkiiippp
If the file has a header, you can use this flag to skip over it.
---rrrooowwwssskkkiiippp
If there is padding at the ends of the rows, you can skip it with
this flag.
---rrrgggbbb ---rrrbbbggg ---gggrrrbbb ---gggbbbrrr ---bbbrrrggg ---bbbgggrrr
These flags let you specify alternate color orders. The default is
---rrrgggbbb.
---iiinnnttteeerrrpppiiixxxeeelll ---iiinnnttteeerrrrrrooowww
These flags let you specify how the colors are interleaved. The
default is ---iiinnnttteeerrrpppiiixxxeeelll, meaning three interleaved bytes make up each
pixel. ---iiinnnttteeerrrrrrooowww means three interleaved rows - a row of red, a row
of green, a row of blue, assuming standard rgb color order. The
---iiinnnttteeerrrppplllaaannneee flag is an obvious extension, but is not implemented.
