Code review comment for lp:~robru/webbrowser-app/packaging

This one needs a patched version of QtWebKit that’s in the phablet-team PPA. Interestingly, it hasn’t been built for raring in the PPA, I’ll request it.

This 'experimental.devicePixelRatio' property doesn’t make much sense on the desktop anyway, so I’ll see if we can make it optional, instead of crashing badly at startup.

Note that this property was introduced to work around an incomplete implementation in QtUbuntu (Qt Platform Abstraction for Ubuntu Touch), so in the long run it is supposed to go away (what is unclear to me is when, I’ll see if I can find out).
