naturally ordered by techniques, shaders, and even GL states since they are also
specified within techniques under passes.
Figure 2.5 is a possible workflow. Advanced engines may differ, but this
schema shows that even the most naive renderer following glTF flow of properties
would de-facto apply fundamental GL principles for ecient rendering, such as
minimizing the number of states changes.
