Intended to be overridden by derived RenderAttrib types to specify how two consecutive RenderAttrib objects of the same type interact.
This should return false if a RenderAttrib on a higher node will compose into a RenderAttrib on a lower node that has a higher override value, or true if the lower RenderAttrib will completely replace the state.
The default behavior is false: normally, a RenderAttrib in the graph cannot completely override a RenderAttrib above it, regardless of its override value–instead, the two attribs are composed. But for some kinds of RenderAttribs, it is useful to allow this kind of override.
This method only handles the one special case of a lower RenderAttrib with a higher override value. If the higher RenderAttrib has a higher override value, it always completely overrides. And if both RenderAttribs have the same override value, they are always composed.
