Perhaps we might want to have non-interactive functionality in QtLauncher in
the future (for performance testing for example)? But I'll remove these, they
don't currently even work correctly.

Without this the view content is not pannable in resizesToContent mode. Easiest
way to make it scrollable again is to enable QGraphicsView scrollbars. This is
not the only or necessarily the best way to do this (see yberbrowser which
implements panning by manipulating graphics items and does not enable
QGraphicsView scrollbars).

When resizesToContents is false (the normal behavior) QWebGraphicsView is
responsible of drawing the scrollbars itself. QGraphicsView scrollbars are
redundant in this case.
