v1.11.1

• Fixed: the settings window could open blank and stay that way. It repaints
  only when something asks it to — when it opens, when it is resized, and
  while a widget is animating — so a first frame that rendered nothing had
  nothing to rescue it. On Windows and Linux a resize almost always follows
  window creation and covered this up by accident; a platform that creates
  the window at exactly the requested size sends none.

  It now keeps asking for frames until one actually renders, and re-points
  the surface at the window whenever the two disagree about its size. If it
  still can't render after a couple of seconds it says so on stderr rather
  than repainting silently forever.

• --settings opens the settings window at startup, instead of needing a
  right-click and a menu entry to get to it.
