      Parameters:
        `view` - The observer's view matrix
        `projection` - The observer's projection
        `x` - A context value passed to `f`
        `f` - The function that will receive the evaluated matrices
      Returns:
        A value of `B`

    - #### transformContext

          public R2TransformContextType transformContext()
