Refactor QMouseEvent to contain the position inside the window

Rename the default accessors for positions to localPos, windowPos
and screenPos, to be explicit about their use.
Introduce a QT_NO_INTEGER_EVENT_COORDINATES define so one can make sure
to always use the float based coordinates.
Fixup all Qt code to use the correct constructor that specifies all
three coordinates.
