• Remote Play full screen fits the screen, on every app. Full screen now sits exactly on the
  window's edges. Before, it was placed in the page instead, so the top and bottom of the picture
  could be cut off even with Fit. The picture is now sized the way a video player sizes
  its video: Fit shows the whole picture at its own shape, with black bars where the screen's
  shape differs; Fill covers the whole screen and crops the edges; Stretch stretches the
  picture to the whole screen. Each one now looks different on every app (Fill and Stretch
  could look the same before).
• Picture size is a menu in full screen. The button on the full-screen bar now shows the
  current size and opens a list (Fit, Fill, Stretch), instead of stepping through them.
  On phones, the Fit / Fill / Stretch row in the ⋯ menu is unchanged.
• On a screen the same shape as the picture (16:9), the three look the same: there is nothing
  to add bars to, crop or stretch.
