* --change to nearest official release version

* Fix viewer.py framebuffer size mismatch. (#2055)

* Fix viewer.py framebuffer size mismatch.

* Change int tuples to mn.Vector2.

* Minor simplifications.

* Replay renderer: add line-rendering and unproject() (#2057)

* integrate DebugLineRender into replay renderers
* add ClassicReplayRenderer.unproject
* stub implementation for BatchReplayRenderer.unproject
* lighting hack in ClassicReplayRenderer to get ReplicaCAD stages to render correctly

* bugfix: cylinder proimitive collsion shape did not use halflength (#2060)

* --have disabled renderer test only execute 1 time (#2065)

* --(Bugfix) Fix normal transformation calc and address backface culling in case of negative scaling/reflections (#2062)

* --don't use co-factor matrix for transforming pre-calculated normals
* --address backface winding in Generic and Phong drawables

TODO :  Still need to set this up in batch renderer.
* --revert change in batch renderer

The normal matrix derivation will be changed in magnum to be appropriate, so we will keep the original verbiage for clarity.  We keep the changes in the default and PBR renderer calls since we need the determinant to determine if winding order must be reversed for backface culling.

* --test negative scaling along 3 axis
* --make copy of observation buffer for ground truth observation

The buffer is shared, so without a copy subsequent observations would overwrite the gt observation buffer.

* Update Magnum submodules to latest. (#2066)

* Update magnum submodules. (#2073)

* Add runtime perf stats for troubleshooting perf problems (#2070)

* add ResourceManager::getDrawableCountAndNumVertices, Sim.get_runtime_perf_stat_values, and related helpers

* --Refactor Semantic Mesh loading/flattening to remove deprecated functionality and improve efficiency  (#2079)

* --refactor to remove deprecated functionality
* --reviewer suggestions;
* --fixed inappropriate alloc

* Articulated object skinning (#2076)

* Add rig property to RenderAssetInstanceCreationInfo.

* Add render_asset to ao_config.json.

* Create render asset from ao_config.json when creating an articulated object.

* Store bone names into MeshTransformNode.

* Add skinning asset loading and phong rendering.

* Assorted minor fixes.

* Add flag to render articulated object primitives while having a skinned mesh for debugging.

* Add skinned articulated object test.

* Fix MetadataMediatorTest

* Cache joint transformations in drawables, other minor fixes.

* Fix test asset path   other minor fixes.

* Fix skinned mesh caching. Make ao_config.json render_asset path relative to the file. Code clean-up.

* --Add access to Scene Instance-level user defined attributes. (#2081)

* --add access to user defined in scene instance configs.

* --If SceneDataset or SceneInstance do not exist, return nullptr.
