Function veloren_voxygen::mesh::greedy::create_quad_greedy

fn create_quad_greedy<M>(
    origin: Vec3<usize>,
    dim: Vec2<usize>,
    uv: Vec2<Vec3<u16>>,
    norm: Vec3<i16>,
    faces_forward: bool,
    meta: &M,
    atlas_pos: Rectangle,
    push_quad: impl FnMut(Vec2<u16>, Vec2<Vec2<u16>>, Vec3<f32>, Vec2<Vec3<f32>>, Vec3<f32>, &M)
)

Precondition: when this function is called, atlas_pos should reflect an actual valid position in a texture atlas (meaning it should fit into a u16).
