Have a widget-based application that uses qTriangulate for fills
and QTriangulatingStroker (and optionally the dash stroke processor)
The resulting triangle (strip) set is visualized on a simple QPainter
canvas, offering the ability to zoom in and examine how the triangulator
behaves on a number of example shapes. It is also possible to step through
and only have the first N set of triangles drawn.
