 /** GrProcessor subclasses should insert this macro in their implementation file. They must then
  *  also implement this static function:
  *      GrProcessor* TestCreate(SkRandom*,
  *                           GrContext*,
  *                           const GrDrawTargetCaps&,
  *                           GrTexture* dummyTextures[2]);
  * dummyTextures[] are valid textures that can optionally be used to construct GrTextureAccesses.
  * The first texture has config kSkia8888_GrPixelConfig and the second has
  * kAlpha_8_GrPixelConfig. TestCreate functions are also free to create additional textures using
  * the GrContext.
