/* A dive plot widget prototype to show proof of concept.
 *
 * Based on example from GUI Programming with Qt4 (Summerfield/Blanchette).
 *
 * We read a dive in from a simple text file and render the dive plot on
 * a QWidget using basic QPainter operations.  We show the colour of the
 * depth profile changing with dy/dx, the ability to fill the enclosed area
 * with a gradient and some simple drawing and text placement.
 *
 * Panning and zooming are pretty much unaltered from the example, with the
 * exception of mods to reverse the direction of the vertical axis to use
 * a "going down means counting up" convention which makes more sense for
 * a dive.
 *
 * Aim is to show proof of concept to non-Qt programmers working on subsurface.
 * Question: what if any capabilities are needed that aren't on show here?
