[AGG] RE: SpanGenerators

[Ivan N. <in...@pd...>]

I am experimenting with 2.4 release and modified SpanGenerator design. The
new functions are a bit easier to use and the concept of a 'renderer' now
seems to be redundant. 

I encountered a problem with 'sbool_combine_shapes_aa' function which still
accepts the 'Renderer' as the last parameter: 

agg::sbool_combine_shapes_aa(agg::sbool_and, sh, ras, sl1, sl, result, ren);

Shouldn't the last parameter be 'render_base' in the new design?
