Possible leak of ArrayBuffers in babylonjs-scene-es6

[dinfuehr]

Hi everyone,

it seems babylonjs-scene-es6 is leaking ArrayBuffer objects. This screenshots are from a heap snapshot after that benchmark ran (e.g. http://localhost:8010/?test=babylonjs-scene-es6 is enough for this). I would expect that the ArrayBuffers get collected by the GC but they stay around in Chrome/Safari/Firefox.

Chrome:

Safari:

Firefox:

Hope this helps!
