categorized logging: trace hover events
Tracing is a kind of logging designed specifically for use with
http://code.qt.io/cgit/qt-labs/umlquick.git, to generate UML
Sequence diagrams. Here it is being used to trace the delivery
of hover events. Due to use of the QT_MESSAGE_PATTERN backtrace
directive, and backtrace splicing, it's not necessary to emit
trace messages for every step: it's mainly important to catch
the final destinations of hover processing, where state is
changed and signals emitted.
