In order to tessellate sphere primitives in the usd reader, like Hydra does, we used the code from
https://github.com/PixarAnimationStudios/OpenUSD/blob/release/pxr/usdImaging/usdImaging/implicitSurfaceMeshUtils.cpp#L41

However, we are still getting tiny discrepancies between both versions, which is failing several tests.
