Set transform for 3DTileset's single feature.

Set TileFeature's color can modify color.is there a way to set feature's transform or matrix to modify feature's position,rientation and scale? Our team want to perform a animation on 3DTileset.
we hava tried to set node's modelMatrix of a tile's _model,but it's not the way we want control features.It's node dvided by tile's BoundingVolume.

Start by tracing the TileFeature and 3DTileset paths involved in feature color, then compare them with the tile _model's node modelMatrix and BoundingVolume behavior described in the issue. The issue does not name files or tests; done would require a decided way to transform an individual feature's position, orientation, and scale without moving the whole tile, suitable for animation.
