• Fix: the eraser ground to a halt after a few seconds of dragging, and
  recovered only when you let go. Two things grew with the length of a
  stroke and multiplied: the whole swept path was repainted every frame,
  and every hole made so far was punched into it again. Only the part that
  moved is repainted now, and only holes that could change a pixel in it
  are punched. Cost per frame no longer grows with the stroke.
• Holes are also spaced by about the eraser's radius rather than every 4
  pixels. They were stacked four deep for no visual gain, and holding the
  eraser still used to add another on every mouse event.
