Artem Pavlenko af2601eea0 1. new style/feature processor abstraction allowing plugable backends.
(to construct custom 'Output' derive from feature_style_processor (CRTP) e.g
	class MyOutput : public feature_style_processor<MyOutput>
     and implement:
	 process(***_symbolizer const&, Feature const&)
     methods
   At the moment only AGG renderer is implemented
