+        <para>
+            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.
+        </para>
+        <para>
+            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.
