* VertexSource virtualizes the AGG "VertexSource" interface
* Transformer is an interface for building pipelines of
VertexSource objects, each taking the output of the previous
object and transforming it in some way
* StrokeTransformer is currently the only implementation and
converts a path into an outline stroke
* PathSource implements the VertexSource interface on top of
a VectorPath which it converts into an agg::path_storage
and into an agg::conv_curve<agg::path_storage> to get smooth
bezier curves
* added VertexSource() to Shape class, which returns the last
object of the transformation pipeline, it uses a PathSource
for the root object
* changed IconRenderer to use the new polymorphic VertexSource
pipeline
