- \brief Migrate Qt GUI to Qt 6.
+ \brief Kernel, Text, Painting, and Utility classes are modified.
Qt 6 is a result of the conscious effort to make the framework more
efficient and easy to use.

Metal, in addition to OpenGL. On Windows the default choice is Direct 3D,
therefore the removal of ANGLE is alleviated by having support for graphics
APIs other than OpenGL as well.

+ \section2 Native clipboard integration
+
+ Qt 5 provided interfaces for integrating platform specific or custom
+ clipboard formats into Qt through \c QMacPasteboardMime in \c QtMacExtras,
+ and \c QWindowsMime from the Windows QPA API. Since Qt 6.6, the
+ equivalent functionality is provided by the classes QUtiMimeConverter for
+ \macos, and the QWindowsMimeConverter for Windows.
+
+ Porting from QWindowsMime to QWindowsMimeConverter requires practically no
+ changes, as the virtual interface is identical. However, in Qt 6 it is no
+ longer needed to register a QWindowsMimeConverter implementation;
+ instantiating the type implicitly registers the converter.
+
+ Porting a QMacPasteboardMime to QUtiMimeConverter requires renaming some of
+ the virtual functions. Note that the \c{QMacPasteboardMime} API used the
+ outdated term \c{flavor} for the native clipboard format on \macos, whereas
+ the platform now uses \c{Uniform Type Identifiers}, i.e. \c{UTI}s, which Qt
+ has adapted for function and parameter names.
+
+ The \c{mimeFor} and \c{flavorFor} functions are replaced by the
+ \l{QUtiMimeConverter::}{mimeForUti} and \l{QUtiMimeConverter::}{utiForMime}
+ implementations, respectively. Those should return the name of the mime
+ type or \c{UTI} that the converter can convert the input format to, so a
+ port usually just involves renaming existing overrides. The
+ \c{convertToMime}, \c{convertFromMime}, and \c{count} functions in
+ QUtiMimeConverter are identical to their QMacPasteboardMime versions.
+
+ The \c{canConvert}, \c{converterName} functions are no longer needed, they
+ are implied by implementation of the above functions, so overrides of those
+ functions can be removed.
+
+ As with the the QWindowsMimeConverter, registration is done by instantiating
+ the type.
