Ability to reuse the PMREM generated texture from scene.environment

Interesting. When the PMREM integration was discussed, it was stated that PMREM is too blocky for background blurriness.

The implementation of my above PR is based on Daniel and Ben PRs which also use the mipmapping approach:

MeshCubeMaterial - cube backgrounds with Blur, HDR Encoding, CubeUV, and ToneMapping support

Just a quick experiment to promote the cube shader to a full material. This all…ows one to blur the background, and use an HDR coded material and also match its tone mapping to the rest of the scene. As I am unsure if this is desired, I have not updated all uses of the "cube" shader to the MeshCubeMaterial. The results look like this - you can adjust the roughness (blur) of the background or its intensity and opacity, and switch between an LDR or HDR cubemap: ![image](https://cloud.githubusercontent.com/assets/588541/16152730/3747c330-3471-11e6-81c5-1d7278981d7f.png) (This is an expansion of this other PR: https://github.com/mrdoob/three.js/pull/9158 )

It’s good that you have posted at #23712 so the difference between PMREM and normal mipmapping can be clarified.
