glRotatef(45, 0, 0, 1)
glTranslatef(0.5, 0, 0)
Transformations are not, in general, commutative.
This means that applying the same transformations in different orders can produce different results.
| no transformation | glTranslatef(0.5, 0, 0) glRotatef(45, 0, 0, 1) | glRotatef(45, 0, 0, 1) glTranslatef(0.5, 0, 0) |

Multiple transformations are effectively applied in reverse order.
i.e., the last transformation (the one immediately before the geometry
function calls) is the first one applied to the raw vertex data.
