Hightlight layer produce a lot of draw calls

[TomaszFurca]

Hi today i saw in my project a lot of draw calls. I just start searching about it and found similar issue: https://github.com/BabylonJS/Babylon.js/issues/2624 with playground https://www.babylonjs-playground.com/#1KUJ0A#75. I think issue still happen in BJS, so please look into that.

But I must admit that I see no problem as the highlight layer needs to render all meshes in the scene to make sure we compute the correct occlusion so it needs to render all meshes to get the correct depth.

You can forcefully deactivate some:

Looks all normal to me to need to render all the element as occluder or highlighter but the in use shader is pretty sheep and it is to a smaller rtt so is is usually ok on small scenes. On bigger scenes it might be nice to exclude every part which is neither emitter nor occluder to boost perf.
