WARNING: -quality depends on the output image file format.
It is different for JPEG than PNG.
The BEST compression results from PNG without going lossy, is
to use a filter like optipng.
-colors 64 is okay but only for thumbnails, and for thumbnails
using -colors 256 is fine.
Once a file is below 1kb is size you don't get any real disk space
saving. A file sill needs at least one full disk block, regardless
of how small its actual size is.
