[SailfishDevel] QML support of Multitouch

[Seppo Tiainen]

In addtition to generating touch events (multi or single), it seems it is
not possible to change the device orientation in the SDK's Sailfish OS
Emulator either. Is this true or is there a way to test switching between
portrait and landscape orientations?
