contentWidth has to be updated before contentX as the WheelArea
underneath will clamp its horizontal value to its bounds on change and
thus break the update to contentX if contentWidth is growing.

As contentX is automatically updated by changes to contentWidth it's
generally a good idea to prevent any reactions to  that with a recursion
guard. When updating contentWidth before contentX this becomes necessary
for correct operation.

The content of the horizontal Flickable element could remain at negative
positions after flicking and generally showed inconsistent behavior.
This was due to the redundant storage of the horizontal offset in
view.startX and flick.contentX. Explicitly assigning contentX from JS
code disables the automatic "rubber" effect which pulls the content back
into the allowed area.
