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

[Keith David Bershatsky]

The latest patch by Anders is working well with the following tests:

(make-frame '(
   (top . 50)
   (left . 50)
   ;; (height . 250.0)
   (width . 250.0)))

(make-frame '(
   (top . 50)
   (left . 50)
   (height . 250.0)
   (width . 250.0)))

(make-frame)

The `top` frame parameter is now respected.  When the `top` and `left` frame 
parameters are not included and `ns-auto-hide-menu-bar` is set to `t`, the 
default position is 0 0, even for large frames that are the size of the display 
-- very good!

The build recipe I used was the latest patch by Martin -- but WITHOUT modifying 
"if (ns_menu_bar_should_be_hidden ()) return frameRect;" -- followed by 
applying the patch from Anders.

Thanks,

Keith
