puzzles: misc. changes and sync with upstream

2017-08-23T18:22:09+00:00

This brings puzzles up-to-date with Simon's tree, along with the
rockbox-specific changes I made. Note that I also got rid of some
of the ugly floating-point code in rbwrappers.c and replaced it
with wrappers for our fixed-point library.

puzzles: fix floating-point formatting

2017-08-16T15:40:42+00:00

This is pretty ad-hoc, but the only other ways are to rewrite
sprintf (which would use too much memory on the c200v2), or
implement support for floats in rockbox's formatter, neither of
which are acceptable.

puzzles: fix star drawing in Signpost

- change point ordering to make concave polygon rendering work
- also enables an "Easter egg" of sorts

puzzles: refactor and resync with upstream

2017-04-29T22:24:42+00:00

This brings puzzles up-to-date with upstream revision
2d333750272c3967cfd5cd3677572cddeaad5932, though certain changes made
by me, including cursor-only Untangle and some compilation fixes
remain. Upstream code has been moved to its separate subdirectory and
future syncs can be done by simply copying over the new sources.

puzzles: more accurate sin() and cos()

2017-01-16T19:54:56+00:00

- now uses fp_sincos()

Fix compilation of puzzles on Windows

2017-01-15T17:30:30+00:00

mingw exports vsscanf and that clashes with rbwrappers' definition.

puzzles: fix a few things

2017-01-05T01:36:04+00:00

- old acos() function was broken, replaced with a call to atan2(); this fixes "Cube!"
- Makefile extended to support building "unfinished games", but not enabled
- a backdrop issue fixed in rockbox.c

Port of Simon Tatham's Puzzle Collection

2016-12-18T17:13:22+00:00

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
