TapAction is a GestureAction-subclass that handles clicks and
tap gestures. It is meant to provide a replacement for ClickAction
using GestureAction:
• it handles events trasparently without capturing them, so that it
can coexists with other GestureActions;
• the ::tap signal is not emitted if the drag threshold is exceeded;
• building upon GestureAction the amount of code is greatly reduced.
TapAction provides:
• tap signal, notifying users when a tap has been performed.
The image-content example program has been updated replacing its
ClickAction usage with TapAction.

The example code that is meant to be XIncluded into the API reference
should not be part of the interactive test suite: it's code that it is
meant to be used as a reference implementation - whereas the interactive
test suite should be allowed to be lean and test behaviour even in nasty
ways. In short: the test suite should not be the place where we show off
idiomatic code for educational purposes.
