-/** @file
-    This file contains specializations for OpenGL of the shader stages declared in
-    include/gpu/GrEffect.h. Objects of type GrGLEffect are responsible for emitting the
-    GLSL code that implements a GrEffect 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 GrEffect&, const GrGLCaps&, GrEffectKeyBuilder*)
-    that is used to implement a program cache. When two GrEffects produce the same key this means
-    that their GrGLEffects would emit the same GLSL code.
-
-    The GrGLEffect subclass must also have a constructor of the form:
-        EffectSubclass::EffectSubclass(const GrBackendEffectFactory&, const GrEffect&)
-
-    These objects are created by the factory object returned by the GrEffect::getFactory().
