bug#21415: 25.0.50; Emacs Trunk -- pixelwise width/height for x-create-frame

[Keith David Bershatsky]

I closed out all the open Emacs instances and the crashing issue is gone, so 
that potential issue is moot.

To sum up the last email, essentially it appears that setting the `height` 
parameter causes `make-frame` to disregard a `top` parameter.

Thanks,

Keith
