59 GrEffect objects *must* be immutable: after being constructed, their fields may not change.
61 GrEffect subclass objects should be created by factory functions that return GrEffectRef.
62 There is no public way to wrap a GrEffect in a GrEffectRef. Thus, a factory should be a static
63 member function of a GrEffect subclass.
65 Because almost no code should ever handle a GrEffect outside of a GrEffectRef, we privately
