scene-ref-attribute: Unity C# attribute for serializing component and interface references within the scene or prefab during OnValidate

Helps to avoid hassle with manually assigning references in the editor. Given the way to provide the scope for finding a component, it should cover the majority of use cases

UnityURP-MobileDrawMeshInstancedIndirectExample

A simplified sample that demonstrates DrawMeshInstancedIndirect API on mobile platforms. Only contains a simple CPU frustum culling (not even a quadtree) -> minimum compute GPU frustum culling (no Acceleration Algorithms), then just 1 DrawMeshInstancedIndirect call.
It also contains a RendererFeature(GrassBendingRTPrePass.cs) to render an offscreen RT(R8), which renders top-down view grass bending area (by trail renderer following moving objects)

Unity Threading; Provides helper APIs for multithreading in Unity.

Provides:
- Simple Threading
- Async Threading: helper methods to access to the Unity main thread or background threads using an async/await style
- Unity Coroutines: helper methods to reduce allocations in Unity coroutines.
- New Coroutines: a reimplementation of Unity coroutines that returns a value type instead to avoid allocations.
- Unity Jobs: helper methods to execute jobs in the Unity Job system.

TextureMerge: Software to merge (or pack) textures into image channels, producing one image with up to four textures.

The tool to prepare assets for a very common optimization technique where you pack up to 4 grey scale textures into one by using different channels to save memory.
