            In the May, 2012 update of the OpenGL 4.2 Specification, all
            APIs using the types GLclampf and GLclampd were modified to
            use GLfloat and GLdouble, respectively, instead. Language
            was added to the Specification requiring that these
            parameters be clamped, when required, at use time rather
            than at specification time.
        </p><p>
            This change allows specifying parameters in ranges
            appropriate for non-fixed-point framebuffers (integer and
            floating-point formats). The change does not require any
            changes to user code calling these functions, because the
            actual underlying types are identical, the behavior is
            externally unchanged, and the header files continue to
            define the old types for compatibility with older code.
