3D Tiles - TileOrientedBoundingBox debug volume should be 2x2x2

[sdgrimm]

I am using OrientedBoundingBox to create 3D Tiles point cloud tilesets with oriented bounding box volumes. It works perfectly. However, when Cesium3DTileset#debugShowBoundingVolume is enabled, the BoxOutlineGeometry is incorrect. The cube being created is 1x1x1, but I believe it should be 2x2x2 to match OrientedBoundingBox. See (https://github.com/AnalyticalGraphicsInc/cesium/blob/3d-tiles/Source/Scene/TileOrientedBoundingBox.js#L123).

Thanks for the report, @sdgrimm. I added this issue to the roadmap, #3241.

A pull request into the 3d-tiles branch with a fix is also very welcome. See Getting Started Contributing if you have time to investigate.

Thanks again for the report, @sdgrimm! This was fixed in #4845 and is now in the 3D Tiles branch.
