Function vec2::transform_mat3

pub fn transform_mat3<'out, T>(
    out: &'out mut [T; 2], 
    v: &[T; 2], 
    m: &[T; 9]
) -> &'out mut [T; 2] where
    T: Add<T, Output = T>,

Example

let mut v = vec2::new_zero();
vec2::transform_mat3(&mut v, &vec2::new_one(),
    &[1_f32, 0_f32, 0_f32, 0_f32, 1_f32, 0_f32, 0_f32, 0_f32, 1_f32],
);
assert_eq!(v, vec2::new_one());
