Implemented manually to maximize performance concerns (it's a hot spot function). However this PR was very relevant to understand what was required to do both in code and from a user perspective. Thanks!!! |

I set "sort by euclidean distance, without considering the bounding sphere radius" as a default policy. In my opinion, it's the best sorting policy for 3D scenes with perspective cameras (the main OGRE usage scenario). In fact, the same policy is used as a default by other engines as well. If this choice is too strict or monocratic, I can add a static
Camera::setDefaultSortModemethod to set the default sorting policy for cameras created from now on (similar to what has been done forMovableObjectandRenderable).
