Volker Hilsheimer 6c726979f7 Turn the "concentriccircles" example into snippets, update screenshot
The example has a lot of code and documentation, but in essence shows
how to use float-based QPainter APIs and how to set a render hint. That
is two lines of code, which we can show as snippets.

Update the screenshot of the example with a higher-resolution version.
