Port of Simon Tatham's Puzzle Collection

Original revision: 5123b1bf68777ffa86e651f178046b26a87cf2d9

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

+Pearl
+<p>
+Draw a single closed loop by connecting together the centres of
+adjacent grid squares, so that some squares end up as corners, some as
+straights (horizontal or vertical), and some may be empty. Every
+square containing a black circle must be a corner not connected
+directly to another corner; every square containing a white circle
+must be a straight which is connected to <em>at least one</em> corner.
+<p>
+Drag between squares to draw or undraw pieces of the loop.
+Alternatively, left-click the edge between two squares to turn it on
+or off. Right-click an edge to mark it with a cross indicating that
+you are sure the loop does not go through it.
