The demo exhibits a sometimes annoying /feature/ to spin the entire
puzzle if a user happens to click and/or drag the mouse somewhere on
the puzzle's background rather than on a puzzle piece.
A new command line option '-n' disables this feature entirely.
The extended menu and keyboard commands learned a new option and
keyboard shortcut 'n' => "Normal Position" to stop spinning and
to reset the puzzle to its original position.
The space key is another (hidden) shortcut for 'n'.

WHAT IS FLTK?
The Fast Light Tool Kit ("FLTK", pronounced "fulltick") is a
a cross-platform C++ GUI toolkit for UNIX(r)/Linux(r) (X11),
Microsoft(r) Windows(r), and MacOS(r) X. FLTK provides
modern GUI functionality without the bloat and supports 3D
graphics via OpenGL(r) and its built-in GLUT emulation. It
was originally developed by Mr. Bill Spitzak and is
currently maintained by a small group of developers across
the world with a central repository in the US.
