#2437
hopefully fix GLKViewController by always using the render thread instead of setNeedsDisplay()
Several Gdx.Net enhancements.
Small changes.
fixing BoundingBox mul

multiplication on bounding box must be set to inf() before using ext().
because a transformation like a translation is not an extension of the bounding box, so ext() is not valid in this case.
boundingbox must be reset with inf() first.
Merge pull request #2469 from titoasty/master
