Merge pull request #178 from Unity-Technologies/enable-gpu-instancing

Enabled GPU instancing on sample material

com.unity.perception/CHANGELOG.md

 
 Parameter, ISampler, and non-generic Sampler class UIs now render properly in MonoBehaviours and ScriptableObjects.
 
+Fixed an issue in the perception tutorial sample assets where upon the editor being first opened, and a user generates a dataset by clicking the play button, the first generated image has duplicated textures and hue offsets for all background objects. Enabling the "GPU instancing" boolean in the tutorial's sample material's inspector fixed this issue.
