Transform2D modifiers do not work as expected

[rand0m-cloud]

These following test cases fail on gdnative = "0.10":

#[test]
fn test_godot_transform2d() {
    use std::f32::consts::PI;

    let position = Vector2::new(250.0, 150.0);
    let rotation = PI / 4.0;
    let transform = Transform2D::IDENTITY
        .translated(position)
        .rotated(rotation);

    let mut transform_2 = Transform2D::IDENTITY.translated(position);
    transform_2.set_rotation(rotation);

    assert_eq!(transform, transform_2);
}

#[test]
fn test_godot_transform2d_2() {
    use std::f32::consts::PI;

    let position = Vector2::new(250.0, 150.0);
    let rotation = PI / 4.0;
    let transform =
        Transform2D::from_rotation_translation_scale(position, rotation, Vector2::ONE);

    let mut transform_2 = Transform2D::IDENTITY.translated(position);
    transform_2.set_rotation(rotation);

    assert_eq!(transform, transform_2);
}

I believe the matrix multiply is backwards in Transform2D::rotated. The function Transform2D::from_rotation_translation_scale also suffers from the above issue, and has a odd argument order for its name.

EDIT: I was mistaken in my belief that xform_basis was not functioning correctly.
