…over Fixes PixarAnimationStudiosGH-3395. As described at https://openusd.org/docs/api/class_usd_geom_point_instancer.html#UsdGeomPointInstancer_protoProcessing PointInstancers can define prototypes under a parent prim specified as an over. The ComputeExtent plugin registered for PointInstancer was not correctly computing prototype bboxes in this case. This extends UsdGeomBBoxCache to allow for a custom prim predicate to be passed, which the updated ComputeExtent plugin takes advantage of to traverse prototype prims in this case.

I took a stab at addressing this, but let me know if I went down the the wrong path |
