graphene:matrix-init-rotate (matrix angle axis)

matrix -- a graphene:matrix-t instance
angle -- a number for the rotation angle, in degrees
axis -- a graphene:vec3-t instance for the axis vector

The initialized graphene:matrix-t instance.

Initializes the matrix to represent a rotation of angle degrees on the axis represented by the axis vector. The angle argument is coerced to a single float before being passed to the foreign C function.
