* 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 git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17896 a95241bf-73f2-0310-859d-f6bbb57e9c96
