/* Draw and paint studio, desktop (1000px and up only). Left rail: the picture library. Centre: the paper, as large as the screen allows.
   Right rail: colours, pencil size, undo / clear. Phone and tablet (<1000px) are untouched.
   The canvas is sized by CSS only (container units on .dpx-stage) and draw.js maps pointer positions with getBoundingClientRect on every event,
   so changing the layout cannot break drawing. The picture library stays inside .dpx-panel in the DOM; it is lifted into the left rail with absolute
   positioning against .dpx-main (the panel is not a positioned element, so the library is not clipped by the panel's scrolling). */
