 /** @file
     This file contains specializations for OpenGL of the shader stages declared in
     include/gpu/GrProcessor.h. Objects of type GrGLProcessor are responsible for emitting the
     GLSL code that implements a GrProcessor and for uploading uniforms at draw time. If they don't
     always emit the same GLSL code, they must have a function:
-        static inline void GenKey(const GrProcessor&, const GrGLCaps&, GrProcessorKeyBuilder*)
+        static inline void GenKey(const GrProcessor&, const GrGLSLCaps&, GrProcessorKeyBuilder*)
     that is used to implement a program cache. When two GrProcessors produce the same key this means
     that their GrGLProcessors would emit the same GLSL code.
 
     The GrGLProcessor subclass must also have a constructor of the form:
         ProcessorSubclass::ProcessorSubclass(const GrBackendProcessorFactory&, const GrProcessor&)
 
     These objects are created by the factory object returned by the GrProcessor::getFactory().
