I found some good opportunities to optmise both pidi-display-pil and, as a consequence, pidi-display-st7789 to avoid drawing calls unless:

  1. The volume changes (and thus the bar needs to be redrawn)
  2. The "progress" advances enough that it will visually change (determined in pixels)
  3. An album art transition is happening
  4. The song state has changed (play/pause)
