On macOS, we don't deliver a press event for the first press on the
track pad (Qt::WA_TouchPadAcceptSingleTouchEvents is not set by default,
so Qt doesn't deliver a single-press on the track pad as a touch event -
that makes some sense or at least maintains compatibility). Because of
that, point 0 is never added to the finger-mapping hash.
When point 0 is then released, we didn't check if we found a valid
iterator for that point ID, and the example crashed.
Fix this by checking that we have a valid iterator before dereferencing,
and by handling Stationary events in the same way as pressed (add the
point to the mapping if it's not already there).

The extra code for using the OpenGL paint engine is significant enough
to be distracting from what the examples are supposed to show. If we
want to show how to use QPainter on an OpenGL widget, then we can make
dedicated and documented examples for that, in the OpenGL category. And
we have such examples in the Qt OpenGL module anyway.
As is, the examples feel more like manual tests of the OpenGL paint
engine; if we need more coverage there, then we can add it there.

We've been requiring C++17 since Qt 6.0, and our qAsConst use finally
starts to bother us (QTBUG-99313), so time to port away from it
now.
Since qAsConst has exactly the same semantics as std::as_const (down
to rvalue treatment, constexpr'ness and noexcept'ness), there's really
nothing more to it than a global search-and-replace, with manual
unstaging of the actual definition and documentation in dist/,
src/corelib/doc/ and src/corelib/global/.

Users should use range constructors instead to do the conversion.
Keep conversion methods between QList and QVector as these will turn
into a no-op in Qt 6, whereas forcing people to use range constructors
would lead to deep copies of the data.
