Don't leave the inner window behind when moving floating windows #73

Previously, EXWM would leave the inner window behind when dragging around floating windows until the mouse was released. Now, the inner window will be dragged along without any lag.

exwm-floating.el (exwm-floating--do-moveresize): drag the inner window along with the outer window.

Yeah, I'm not sure if it was intentional (performance issues?) or just a bug. But Emacs is definitely fast enough to handle it now.

I had always assumed that this was left out for performance reasons - maybe the interaction of the X server and Emacs as you said, or just slower blitting back then. Iirc some historical WMs also didn't move the window and only moved a thin border. But it works very well now and your patch was simple enough.

Specially when resizing would resize both the frame and the X window. Thank you.
