Aside: is the texture fixed or does it change as the model moves?

There is a fixed correspondence between vertices of the mesh on the left, and points in the texture image on the right. Each vertex has a (U,V) attribute that is independent of vertex position. So if one were to rotate the mesh / vertices around or deform the mesh by moving vertices around in some way, the mapping between vertices and (U,V) coordinates would not change.
