Use testlib for multiPointRawEventTranslationOnTouchScreen events

It was an old test written in a very low-level way, which perhaps is ok
to be independent of testlib in a few tests; OTOH, it was blacklisted
on a couple of platforms. Perhaps doing touch events the standard way
could be more stable.

While we're at it:
- verify that the touch events are accepted, and thus verify the new
  bool return value from commit()
- implement paintEvent() to help understand the layout, and touchpoint
  locations
- remove repeated QCOMPARE lines
- skip the test if window positioning fails
- try to un-blacklist it, on the assumption that window positioning
  failure was the reason
