Inconsistent realign() and emit realigned() behavior?

[PCMan]

While trying to implement NETWM icon geometry for the task bar buttons, I noted that there is a problem.
In LxQtPanel, there are a lot of places emit realigned() is called, and in some places only realign() is called and the signal is not emitted. This caused some inconsistency.
When you setPosition() or setLength(), only "emit realigned()" is called, but the panel is not yet resized, so in Plugin::realign() the panel is still in its old geometry. However, in showEvent(), realigned() is trigerred after calling realign(), so when Plugin::realign() is called, the panel is already in its new geometry and that causes inconsistency.
What's the state of the panel when Plugin::realign() is called? prepared to resized and repositioned and have the old state, or it's already realigned?

What if I want to do something AFTER the panel is already realigned and its geometry is already changed? How can I ensure that?
I tried to install a timer in Plugin::realign() but that's not reliable since I'm not sure when will the panel really get its new state after realign() is called.

Just did a PR for that. emit realigned is now called always AFTER LxQtPanel::realign().
The signal will call Plugin::realign() so you can be sure that everything is realigned when this function is called.
Hope that solves the problem!
