Better atom layout options

[White-Rabbit-Scientific]

Using the new Atoms layout (AllocatedAtomLayout) is there a way to lay out atoms vertically? I'm thinking for example of buttons with text plus an image.

I see that there is a private Align2.

/// Instructions for painting an [`AtomLayout`].
#[derive(Clone, Debug)]
pub struct AllocatedAtomLayout<'a> {
    pub sized_atoms: SmallVec<[SizedAtom<'a>; ATOMS_SMALL_VEC_SIZE]>,
    pub frame: Frame,
    pub fallback_text_color: Color32,
    pub response: Response,
    grow_count: usize,
    // The size of the inner content, before any growing.
    desired_size: Vec2,
    align2: Align2,
    gap: f32,
}
