Utility to merge sprites and generate the spritemap.json for PixiJS.

spritemap.py [-h] [-v] [-o OUTPUT] [-i INPUT [INPUT ...]]

By default, spritemap will combine input/* and create spritesheet.png, spritesheet.json in output/:

> python spritemap.py
Packed Density:  91 %

Common paths will be removed from the frame name. input/ship.png will be ship.png

You can also feed spritemap multiple input directories, and the output frames will be prefixed with uncommon path components:

> python spritemap.py -i redteam/* blueteam/*
Packed Density:  97 %

So redteam/ship.png and blueteam/ship.png will not conflict and will be named redteam.ship.png and blueteam.ship.png
