Rewrote VectorRendererSpec & VectorRendererAA to use a Graphics::PixelFormat, instead of relying on color masks -> should fix bug #2537212, possibly at a slow down on low-end systems (a regression which we certainly could resolve, though). Note: I left the PixelType template param in on purpose, in case we want one day to compile in both 16 and 32 bit pixel support simultaneously
