v1.26.2

Version 1.26.2

Faster on phones:

- Menus open in about half the time: the notation sits in a document of
  its own, out of reach of Nextcloud's style rules.
- Playback no longer re-renders the toolbar on every note, and following
  the cursor reads no layout.
- Pinch zoom follows the fingers (Galaxy S23: 50 instead of 37 fps on the
  pages, 39 instead of 27 in the system band).
- Opening a score and turning pages block the screen less; the system
  band prepares the next systems while idle.
