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

[Keith David Bershatsky]

Thank you both so very much for making feature request 21415 a reality and for 
fixing the various issues along the way.  I built Emacs this morning from the 
master branch for both OSX 10.6.8 and Windows XP -- i.e., through 
"6d6bf466477b004035a4314886e35214c6f8603b", which is subsequent in time to the 
commit by Martin earlier in the day.

Both of the builds (i.e., OSX and Windows XP) are working well with the tests 
that I performed using the `default-frame-alist` and the new `text-pixels` 
specifications for `width` and `height`.
