FSX/P3D have a nice feature to follow a remote aircraft with the camera.
X-Plane was missing this feature, since for X-Plane the remote aircrafts
are not known. However, from a plugin point of view, we know them and where
they are. So we can manually control the camera and provide a similar
feature.
This is still very simple. As soon as you move the mouse, the PoV angle will
change. In future updates, it should be change only while the right mouse
button is pressed.
QtDBus was the main component of xswiftbus' Qt dependency. This is the
first preparation step to get xswiftbus Qt free.
The new implementation is based on the low level libdbus library, which
was also in use by QtDBus itself. But instead of QtDBus, we use now a thin
C++ wrapper. To keep DBus handling async, libevent is used to monitor
timeouts and fds.
Summary:
I wanted to rename xbus because its relation to //swift// is not immediately clear from the name.
xswiftbus seems reasonable.
