+ *
+ *      Set the value of successive shader constants.
+ *
+ *      Shader constants are analogous to uniform variables in GLSL,
+ *      except that they belong to the render context rather than to
+ *      an individual shader.
+ *
+ *      Constants may have one of three types: A 4-vector of floats,
+ *      a 4-vector of integers, or a single boolean flag.
+ *
+ * Results:
+ *      None.
+ *
+ * Side effects:
+ *      None.
