Override this if your subclass needs to record data that it will need to recreate itself from its CreateProc (returned by getFactory()).
DEPRECATED public : will move to protected ... use serialize() instead

Returns true if the shader is guaranteed to produce only opaque colors, subject to the SkPaint using the shader to apply an opaque alpha value. Subclasses should override this to allow some optimizations.
