Three.js: computeBoundingBox error when filling BufferGeometry

[daylanKifky]

Description of the problem

I created a fixed length buffer, and then gradually filled it with vertices that come from a data stream to display a pointCloud.

If I try to computeBoundingBox() on the BufferGeometry it includes all the empty points on the buffer making the boundingBox extend until (0,0,0).

I would expect this to be restricted by the BufferGeometry.drawRange

The drawRange has no effect when computing the bounding volumes. In this case, you have to perform a manual computation.
