- square sine tick and tock sounds (more annoying, more useful;-)
- optical indication of tics on display
- unification of mode of operation for SWCODEC and HWCODEC (tested on simulator)
  Both playback and display drawing happen in main loop, always.
- operating in two modes now:
-- 1. classic dumb metronome
--- active when openened as application without file to open
--- the usual functionality with tapping and bpm change
--- controls indicated on display
-- 2. track mode with programmable series of parts
--- active when started as viewer for a .tempo file
--- differing meters (4/4, 3/4, 6/8, etc.)
--- patterns (tick/tock/silence on each beat)
--- smooth tempo changes in those tracks

This version had lots of testing regarding metronome accuracy,
resulting in the realization that PLL A and PLL B differ
on the Clip+, causing drift. There is still drift when the timer
intervall is too small, so I settled on 2 ms as compromise.

This is the final version, after adding documentation and extensive
help from Sebastian Leonhardt testing it on slower hardware (YH820),
where it works up to 650 actual bpm with display indication.

Latest change: Documentation nitpicks.

This work is based on:
- Fabien Sanglard's "Fabother World" based on
- Piotr Padkowski's newRaw interpreter which was based on
- Gregory Montoir's reverse engineering of
- Eric Chahi's assembly code

--------------------------------------------------------------------
Progress:

* The plugin runs pretty nicely (with sound!) on most color targets
* Keymaps for color LCD targets are complete
* The manual entry is finished
* Grayscale/monochrome support is NOT PLANNED
  - the game looks horrible in grayscale! :p

--------------------------------------------------------------------
Notes:

* The original game strings were built-in to the executable, and
  were copyrighted and could not be used.
* This port ships with an alternate set of strings by default, but
  can load the "official" strings from a file at runtime.

--------------------------------------------------------------------
To be done (in descending order of importance):

* vertical stride compatibility                          <30% done>
* optimization                                           <10% done>
