also mention how this is shared between different GL painters. something like
sharing util methods and context_.

I'm not quite sure if I understand... The static methods are of course shared,
but the context_ is not necessarily shared (is an instance field, not static).
When I use the painters in shader_bench, I set the contexts all to be the same,
but I could have set them to different contexts.

+ public:
+  virtual void SetGLContext(gfx::GLContext* context);
+ protected:
+  static GLuint LoadShader(gfx::GLContext* context, unsigned type,
+                           const char* shader_source);
+  static GLuint CreateShaderProgram(gfx::GLContext* context,
+                           const char* vertex_shader_source,
+                           const char* fragment_shader_source);
+  gfx::GLContext* context_;
+};
