Detailed Description

template<typename PixelType>
class Graphics::VectorRendererAA< PixelType >

VectorRendererAA: Anti-Aliased Vector Renderer Class

This templated class inherits all the functionality of the VectorRendererSpec class but uses better looking yet slightly slower AA algorithms for drawing most primitives. May be used in faster platforms.

TODO: Expand documentation.
