* Don't set a limit for image size (Qt6 had set an allocation limit of 256 MiB).
* Fixed invalid nullptr parameter in QObject::connect (and so, silenced a warning).
* Fixed a small miscalculation in the selection screenshot.
* Ensure the current thumbnail is in the visible part of the thumbnail bar.
* Fixed a problem in rectangular annotations.
