Detailed Description

Definition of a functor for calculating the hashcode of a Pass.

Remarks
The hashcode of a Pass is used to sort Passes for rendering, in order to reduce the number of render state changes. Each Pass represents a single unique set of states, but by ordering them, state changes can be minimised between passes. An implementation of this functor should order passes so that the elements that you want to keep constant are sorted next to each other.
