Provides utility functions for managing uniforms.
src -- An object representing uniform definitions.
Clones the given uniform definitions by performing a deep-copy. That means if the value of a uniform refers to an object like a Vector3 or Texture, the cloned uniform will refer to a new object reference.
uniforms -- An array of objects containing uniform definitions.
Merges the given uniform definitions into a single object. Since the method internally uses .clone(), it performs a deep-copy when producing the merged uniform definitions.
