-/**
- * Implements GrBackendProcessorFactory for a GrProcessor subclass as a singleton. This can be used
- * by most GrProcessor subclasses to implement the GrProcessor::getFactory() method:
- *
- * const GrBackendProcessorFactory& MyProcessor::getFactory() const {
- *     return GrTBackendProcessorFactory<MyProcessor>::getInstance();
- * }
- *
- * Using this class requires that the GrProcessor subclass always produces the same GrGLProcessor
- * subclass. Additionally, it adds the following requirements to the GrProcessor and GrGLProcessor
- * subclasses:
- *
- * 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
- *    MyProcessor::GLProcessor::emitCode().
- * 3. MyProcessor must have a static function:
- *      const char* Name()
- *    which returns a human-readable name for the processor.
