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

+Tracks
+<p>
+Complete the track from A to B so that the rows and
+columns contain the same number of track segments as are indicated in the
+clues to the top and right of the grid. There are only straight and
+90-degree curved rail sections, and the track may not cross itself.
+<p>
+Left-click on an edge between two squares to add a track segment between
+the two squares. Right-click on an edge to add a cross on the edge,
+indicating no track is possible there.
+<p>
+Left-click in a square to add a colour indicator showing that you know the
+square must contain a track, even if you don't know which edges it crosses
+yet. Right-click in a square to add a cross indicating it contains no
+track segment.
+<p>
+Left- or right-drag between squares to lay a straight line of is-track or
+is-not-track indicators, useful for filling in rows or columns to match the
+clue.
