Code freeze break request for Pango

[Behdad Esfahbod <behdad behdad org>]

Hi,

I'm lazy...

So, this cycle I rewrote most of the internals of the PangoFc backend.  Mostly
for optimization, also to fix bugs.  This changed some of the backend-only
API.  Since yesterday I've been putting the finishing touches on this work and
had to make a few changes.  One of them involves a minor API addition to the
backend-only API.  The others are fixes here and there.  So here I am asking
for permission to push these to pango:

    [pango-coverage] Remove unused struct member

    [pangofc] Add a "fontmap" property to PangoFcFont

    Gecko uses its own PangoFcFontMap subclass with its own PangoFontSet.
    Previously we were setting font->fontmap in our own private
    PangoFcFontSet.  Now it's up to the PangoFcFont subclass to set it
    when creating the new font object.

    Also adds the following backend-public symbol:

        pango_fc_font_map_find_decoder()


As a bonus, I'm not documenting the internal workings of pangofc-fontmap.c.

Cheers,
