Rotates the vertices of a Face to the given angle.
The actual vertex positions are adjusted, not their transformed positions.
Therefore, this updates the vertex data directly.
The Face to rotate.
The angle to rotate to, in radians.
Optional
An optional center of rotation. If not given, the Face in-center is used.
Rotates the vertices of a Face to the given angle.
