[Development] Source incompatible Qt 5 change: Removing the QTouchEvent::TouchPoint::Primary flag

[Samuel Rødal]

Hello,

I'd like to remove the QTouchEvent::TouchPoint::Primary flag, as per 
change request http://codereview.qt-project.org/#change,12928

The current purpose of the flag is simply to note that a touch point is 
duplicated as a mouse event by the windowing system (to prevent Qt from 
also generating a synthesized mouse event from that touch event). The 
linked change moves this duplication logic out of the windowing system 
interface (platform plugins, generic plugins, etc), and into QtGui.

If we kept it as always returning false it could mask incorrect behavior 
in the user application.
