   The paper gets all the space the controls don't need. Controls sit at the edges,

   - Landscape: side rails. Tools and colors are on the non-drawing hand's side (left for
     right-handers, like Procreate's sidebar); undo and actions are on the other side.
     Height is the scarce dimension on an iPad mini in landscape, so nothing goes on top.
   - Portrait: a slim action bar on top, tools and colors along the bottom. */
