I wonder if there isn't a missing XINT somewhere.  Here's my default
face:

Face: default (sample) (customize this face)
Documentation: Basic default face.
Defined in `faces.el'.

        Family: DejaVu Sans Mono
       Foundry: unknown
         Width: normal
        Height: 96
        Weight: normal
         Slant: normal
    Foreground: #000000
    Background: #ffffff
     Underline: nil
      Overline: nil
Strike-through: nil
           Box: nil
       Inverse: nil
       Stipple: nil
          Font: #<font-object -unknown-DejaVu Sans Mono-normal-normal-normal-*-12-*-*-*-m-0-iso8859-1>
       Fontset: -unknown-DejaVu Sans Mono-normal-normal-normal-*-12-*-*-*-m-0-fontset-auto2
       Inherit: unspecified

Note that "Height: 96" but the XLFD, contains "-12-" in the pxlsz
field.  Note that

#define XINT(a) (((EMACS_INT) (a)) >> GCTYPEBITS)

and

#define GCTYPEBITS 3

on my platform, thus

XINT(96) == 96 >> 3 == 96/8 == 12

Is the :height key in a font-spec supposed to be a Lisp integer?
Seems like an ugly thing to put the user through.

I will continue to debug this.
