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

The latest patch was successfully applied, and building occurred without incident.

When using the setting of `(setq ns-auto-hide-menu-bar t)` and a `make-frame` with pixelwise parameters for width/height, the result when creating large frames -- (width 1909.0) (height . 1060.0) -- is a frame that is one-half above the screen (out of sight) and one-half of the frame is showing.  Adding a parameter of (top . 0) has no affect.

The pixelwise frame parameters of width/height for `make-frame` are not behaving precisely -- e.g., a height specification of (height . 1059.0) is 14 pixels shy of filling the entire screen [i.e., 1066 pixels outer width]; and a height specification of (height . 1060.0) is 6 pixels larger than the full screen [i.e., 1086 pixels outer width].  It is not presently possible to create a frame that precisely fills the entire screen using the patch as-is.
