[Interest] native resolution on iOS

[Hamish Moffatt]

We have an iOS application running using Qt 4.8. We used Mediator 
Software's Qt4IOS/CuteIOS work. Our application is purely widgets (no QML).

This gave us native resolution on iPhone (480x320 on old models, 
640x960, 640x1136 etc), and scaled resolution on iPad (1024x768 
regardless of model), which suited us quite well.

Now we're porting to Qt 5.4 and native iOS support. I haven't done 
anything to enable native/hiDPI mode, and I'm getting 320x480 and 
320x568 on the Retina models, while I'd really like to see the full 
native resolution.

How do I enable full resolution? And can I do that on iPhone only?

thanks,
Hamish
