S - Pixel Ship
Pixel Ship sizes an image in proportion to its original size. It decimates the image
by shipping only certain, regularly spaced pixels.
Example: 4S would transmit every fourth pixel from every fourth line.
The smaller number of pixels shipped, the smaller the image, however, after a
certain point the image becomes unusable.
