FoamTree 1.0.x emulation

This example configures FoamTree 3.x to emulate the look and feel of the Flash-based 1.0.x line as closely as possible. Please note that FoamTree 1.0.x uses a different polygon layout paradigm, so it's not possible to for FoamTree 3.x to produce the shapes, such as non-convex polygons, known from the 1.0.x line.
