this is "unexpected". basically a window manager will expect type to be fixed
before show of window. so changing while a window is visible will have most
likely bizarre if ANY effects in a wm. i'ts a very unexpected change and i
really don't think it's wise for apps to change it after window is shown.

that's why elm only lets u set it on creation - it's kind of hinting that u
never want to change it after that as its a "bad idea" :)
