Description
Adjusts the BatchedMesh frustum culling logic to use only the bounding sphere as Frustum.intersectsObject does (I missed this previously). This improves the time to perform frustum culling performance only by over 3x (sorting disabled). Between this and #27213 - the execution time of onBeforeRender can come down significantly from what was reported in #27202.
