Visualization system to explore influenza sequence data.

Light gray is used to display unselected points.  A yellow outline is
used to highlight the selection.

  ESC: Clear selection.

  Right-click, drag: Pan.

  CTRL + Left-click, drag and release: Add box to selection.

  s: Selection will be used to define a set.

  z: Selection will be used to define a zoom region.

  r: Reset the display (unzoom).

  l: Toggle display of the legend (on by default).

  Mouse-wheel: scroll to zoom in or out by 10% of the window size with
  the focus at the center of the window.

An attempt was made to use the glutPassiveMotionFunc to show the
information for the data under the mouse pointer.  This proved to be
too slow so the use of this technique was discarded.  The basic
selection mechanisms can be used to identify the points under the
mouse.  Alternatively a keyboard command might be added to provide the
information upon a keypress.
