=== Resizing containers
By clicking and dragging the border of a container, you can resize it freely.
By clicking and dragging the border of a container, you can resize the whole column
(respectively row) which this container is in. This is necessary to keep the table
layout working and consistent.
TODO
Currently, only vertical resizing is implemented.
The resizing works similarly to the resizing of floating windows or movement of floating
windows:
* A new, invisible window with the size of the root window is created (+grabwin+)
* Another window, 2px width and as high as your screen (or vice versa for horizontal
resizing) is created. Its background color is the border color and it is only
there to signalize the user how big the container will be (it creates the impression
of dragging the border out of the container).
* The +drag_pointer+ function of +src/floating.c+ is called to grab the pointer and
enter an own event loop which will pass all events (expose events) but motion notify
events. This function then calls the specified callback (+resize_callback+) which
does some boundary checking and moves the helper window. As soon as the mouse
button is released, this loop will be terminated.
* The new width_factor for each involved column (respectively row) will be calculated.
