bool OEReduceSurface(OESurface &reducedSurface,
                     const OESurface &original,
                     unsigned int targetNumberOfVertices,
                     unsigned int type = OEEdgeReductionType::MinimumDistance)

Takes a surface and creates a new surface from it, with the new surface having a reduced number of vertices and triangles. The targetNumberOfVertices argument supplies a value for the desired number of vertices for the returned surface. The overall quality of the new surface will depend on this value, with smaller values giving lower quality surfaces. Currently only one edge reduction method is supported (OEEdgeReductionType.MinimumDistance). Returns true if the returned surface contains the requested number of vertices.
