cinera: Fix mobile scrolling and centring

This commit fixes spurious scrolling in DeriveReliableWindowDimensions()
on mobile. It also fixes centring of Vimeo videos on mobile.

In addition, it replaces some deprecated JavaScript:
•   window.orientation → screen.orientation.type
•   window.onorientationchange → screen.orientation.onchange
