Public bug reported:

Opening the camera app, which by default is fullscreen, the unity8 log
shows that the camera-app surface height is being animated, which is a
waste of effort. Resizing Qt aps isn't particularly fast.

Instead the correct surface size should be set once, and shell animates
the panel  per usual.
