Transforms a #graphene_plane_t p using the given matrix
and normal_matrix.
If normal_matrix is null, a transformation matrix for the plane
normal will be computed from matrix. If you are transforming
multiple planes using the same matrix it's recommended to compute
the normal matrix beforehand to avoid incurring in the cost of
recomputing it every time.
