  Target error is an approximate measure of the deviation from the original mesh using distance normalized to 0..1 (so 1e-2f means that simplifier will try to maintain the error to be below 1% of the mesh extents). Note that because of topological restrictions and error bounds simplifier isn't guaranteed to reach the target index count and can stop earlier.

  This algorithm will not stop early due to topology restrictions but can still do so if target index count can't be reached without introducing an error larger than target. It is 5-6x faster than `meshopt_simplify` when simplification ratio is large, and is able to reach ~20M triangles/sec on a desktop CPU (`meshopt_simplify` works at ~3M triangles/sec).
