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

[Keith David Bershatsky]

I had an opportunity this evening to test out the earlier patch by Martin in 
this thread for the floating point frame-creation on Emacs built for MS-Windows 
(XP--SP3) and it is working well.  I've set up the `default-frame-alist' with 
floating points for height and width, and the initial frame and all new frames 
perfectly reflect the parameters tested -- what a pleasure -- :)

I wasn't sure if anything had changed in the past couple of weeks, so I did a 
hard reset back to the last commit on September 11, 2015 and then applied the 
patch to do my testing.
