Only recent IBus versions have support for this signal
which is used for wayland clients. In order to work
with older IBus versions we can silently ignore the
signal's absence.

IBus now provides a new method for cursor positioning where the
coordinates are relative to the focused window. This is useful for
wayland clients which don't have access to their global coordinates.

Right now we have three "dummy cursor" widgets between the background
menu, the message tray menu, and the IBus candidate popup. Consolidate
these into one "dummy cursor" widget which is tracked in the layout
manager.
After moving the dummy source actor, we still have to poke the
boxpointer so that it gets repositioned.
This has always been broken but went unnoticed until now since none of
the commonly used engines currently depend on this method. Thanks to
Mathieu Bridon for pointing it out.

setCandidates() has too many arguments and setting the orientation
isn't particularly related with it. It might also be useful to switch
orientation without changing the candidates.

Make it look more like the mockups.
In order to do that we stop using PopupMenu and friends as it doesn't
really buy us anything and just makes it more cumbersome to add the
style classes we need.
