Benchmark wxIMAGE_QUALITY_BOX_AVERAGE too for completeness

Browse source 
Check the speed of wxImage::Scale() using this algorithm too.

As expected, it's between normal and high quality when upscaling and
exactly the same as high quality when shrinking (because it is actually
the algorithm used for shrinking for wxIMAGE_QUALITY_HIGH).
