I forward X halfway around the world and the mouse move/resize as implemented
in dwm brings things to a screeching halt.
I noticed that the non-solid move/resize in evilwm works much better because
it doesn't demand the client to redraw a billion times as you drag the mouse
because it just draws a wire frame of the window as you drag.
I have included a patch for dwm-5.8.2 in which I basically stole the wire
frame move/resize code from evilwm and adapted it for dwm.
If anyone is interested I'll do a patch for a more modern release.
