MIT Licensed. Some games still crash and others are unplayable due to
issues with controls. Still need a "real" polygon filling algorithm.

Currently builds one plugin per puzzle (about 40 in total, around 100K
each on ARM), but can easily be made to build a single monolithic
overlay (800K or so on ARM).

The following games are at least partially broken for various reasons,
and have been disabled on this commit:

Cube:     failed assertion with "Icosahedron" setting
Keen:     input issues
Mines:    weird stuff happens on target
Palisade: input issues
Solo:     input issues, occasional crash on target
Towers:   input issues
Undead:   input issues
Unequal:  input and drawing issues (concave polys)
Untangle: input issues

Features left to do:
 - In-game help system
 - Figure out the weird bugs

# Crop one image into another, after first checking that the source

# This is used in the Puzzles icon build scripts to construct icons
# which are zoomed in on a particular sub-area of the puzzle's
# basic screenshot. This way I can define crop areas in pixels,
# while not having to worry too much that if I adjust the source
# puzzle so as to alter the layout the crop area might start
# hitting the wrong bit of picture. Most layout changes I can
# conveniently imagine will also alter the overall image size, so
# this script will give a build error and alert me to the fact that
# I need to fiddle with the icon makefile.
