  - [geometry-1] setting a matrix to identity with setters keeps is2D `true`. Creating a matrix with a 16-number identity sequence sets `is2D` to `false`. (by trusktr)
    https://github.com/w3c/fxtf-drafts/issues/588 
  - [geometry-1] `DomMatrixReadOnly` is missing `preMultiply()` method (and the idea of better mutable vs immutable patterns) (by trusktr)
    https://github.com/w3c/fxtf-drafts/issues/587 
  - [geometry-1] Methods of immutable classes should return immutable instances. (by trusktr)
    https://github.com/w3c/fxtf-drafts/issues/586 
  - [geometry-1] propose adding DOMPoint as an argument for DOMMatrix that accepts vectors. (by trusktr)
    https://github.com/w3c/fxtf-drafts/issues/585 
  - [geometry-1] There is no way to reset `DOMMatrix` `is2D` back to `true` when returning to identity. (by trusktr)
    https://github.com/w3c/fxtf-drafts/issues/584 
  - [geometry-1] Why does `multiplySelf` just accept another `DOMMatrix`? (by trusktr)
    https://github.com/w3c/fxtf-drafts/issues/582 
  - [geometry-1] What's the point of `DOMMatrixInit` if the `constructor` cannot accept such a value? (by trusktr)
    https://github.com/w3c/fxtf-drafts/issues/581 
  - [geometry-1] Steps for `multiplySelf` are inefficient (by trusktr)
    https://github.com/w3c/fxtf-drafts/issues/580 
  - Improve algorithm steps for identity transforms (by trusktr)
