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.
Pick-to: 6.7 6.6
Fixes: QTBUG-119983
Change-Id: Iafcb813dff6ab8c269176f7994c95947ebf5e559
