1.2.5.0

Improvements

SceneReader : Improved performance when computing bounds for complex USD stages containing scenegraph instancing.

SceneReader :
- Fixed rounding errors which could cause the wrong sample to be read from a USD file. This was particularly noticeable for non-interpolable attributes such as visibility.
- Fixed transforms loaded from USD files using the UsdGeomXformable::ResetXformStack operator.
SceneWriter : The UsdShadeMaterialBindingAPI schema is now applied to all prims with material bindings, making the written files compatible with USD_SHADE_MATERIAL_BINDING_API_CHECK=strict mode.
