This patch replaces the first instance of QCOMPARE with QTRY_COMPARE /
QVERIFY with QTRY_VERIFY after a call to QWidget::grabGesture.
It re-groups verifications so that the verification of the highest
event count is on top.
The test function customGesture is skipped if
QGestureManager::deliverEvents cannot establish a target to deliver
the custom event.
