  * Using this class requires that the GrProcessor subclass always produces the same GrGLProcessor

  * subclasses:
  *
- * 1. The GrGLProcessor used by GrProcessor subclass MyEffect must be named or typedef'ed to
- *    MyEffect::GLProcessor.
- * 2. MyEffect::GLProcessor must have a static function:
- *      EffectKey GenKey(const GrProcessor, const GrGLCaps&)
+ * 1. The GrGLProcessor used by GrProcessor subclass MyProcessor must be named or typedef'ed to
+ *    MyProcessor::GLProcessor.
+ * 2. MyProcessor::GLProcessor must have a static function:
+        void GenKey(const GrProcessor&, const GrGLCaps&, GrProcessorKeyBuilder* b)
  *    which generates a key that maps 1 to 1 with code variations emitted by
- *    MyEffect::GLProcessor::emitCode().
- * 3. MyEffect must have a static function:
+ *    MyProcessor::GLProcessor::emitCode().
+ * 3. MyProcessor must have a static function:
  *      const char* Name()
- *    which returns a human-readable name for the effect.
