From Mike Wittman, "This is another weirdo change to support code generation. It brings all the Drawable::supports and Drawable::accepts overloads into the ShapeDrawable scope to avoid errors invoking the ones that are not defined in ShapeDrawable. Currently you'll get compilation errors if you pass a Drawable::AttributeFunctor or PrimitiveIndexFunctor to the "accept" function invoked on a ShapeDrawable pointer or reference, since those overloads are only defined in the base class. You'll also get the same error passing a PrimitiveIndexFunctor to the "supports" function. These errors occur because C++ function overload resolution does not cross inheritance boundaries."
