This can be used in the Shader parameter of GFX.Feature or the EntryPoint parameter of GFX.EffectPass.
The functions differently when used in the Vertex stage and the Fragment stage of the entry point.
- When used in the vertex stage, this shard will read the value of the vertex attribute specified in the Name parameter.

This shard is able to read a vertex attribute even if it was not explicitly written and output in the vertex stage using Shader.WriteOutput.
