70 GrEffect objects *must* be immutable: after being constructed, their fields may not change.
72 GrEffect subclass objects should be created by factory functions that return GrEffectRef.
73 There is no public way to wrap a GrEffect in a GrEffectRef. Thus, a factory should be a static
74 member function of a GrEffect subclass.
76 Because almost no code should ever handle a GrEffect directly outside of a GrEffectRef, we
