           Summary: FcFreeTypeQueryFace fails on postscripts fonts loaded
                    from memory
        QA Contact: freedesktop at behdad.org
          Severity: major
    Classification: Unclassified
                OS: All
          Reporter: nfxjfg at gmail.com
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: library
           Product: fontconfig

Trying to use a PostScript Type 1 font with FcFreeTypeQueryFace() fails. The
function returns NULL.

It appears the reason is that FcFreeTypeQueryFace uses FT_Load_Sfnt_Table to
hash the font data, which works for TrueType and OpenType fonts, but not for
other fonts. (It then proceeds trying to open the name as a file, which makes
absolute no sense for memory fonts.)

I fail to understand why not being able to hash the font would make fontconfig
try to open (essentially) random files and fail to provide the font to the
application.

Tested with git 03216ccf4ca0 and the latest release.
