Structures representing abstract fonts.

<para>
Pango supports a flexible architecture where a
particular rendering architecture can supply an
implementation of fonts. The #PangoFont and
#PangoCFont structures represent an abstract
rendering-system-indepent font, and a
<firstterm>component</firstterm> of such a font,
respectively.
</para>
<!-- ##### SECTION See_Also ##### -->
<para>
</para>
<!-- ##### STRUCT PangoFont ##### -->
<para>
The #PangoFont structure is used to represent
a font in a rendering-system-independent matter.
To create an implementation of a #PangoFont,
the rendering-system specific code should malloc
a larger structure that contains a nested
#PangoFont, fill in the klass member of
the nested #PangoFont with a pointer to
a appropriate #PangoFontClass, then call
pango_font_init() on the structure.
</para>
<para>
The #PangoFont structure contains one member
that may be accessed by derived classes:
<informaltable pgwide=1 frame="none" role="struct">
<tgroup cols="2"><colspec colwidth="2*"><colspec colwidth="8*">
<tbody>
<row>
<entry>#PangoFontClass *klass;</entry>
<entry>a pointer to the <firstterm>class structure</firstterm>
for this font.</entry>
</row>
</tbody></tgroup></informaltable>
</para>
<!-- ##### STRUCT PangoFontClass ##### -->
<para>
The PangoFontClass structure contains the virtual
functions for an implementation of a a PangoFont.
It contains the following member:
<informaltable pgwide=1 frame="none" role="struct">
<tgroup cols="2"><colspec colwidth="2*"><colspec colwidth="8*">
<tbody>
<row>
<entry>void (*destroy) (#PangoFont *font);</entry>
<entry>a function to free the font structure and associated resources.</entry>

<para>
The #PangoCFont structure is used to represent a single componenent
of a font n a rendering-system-independent matter. A component of a
font is an opaque object that makes sense only to the rendering
system. A glyph (the #PangoGlyph structure) is stored as a #PangoCFont
and a numeric glyph index.
</para>
<para>
To create an implementation of a #PangoCFont,
the rendering-system specific code should malloc
a larger structure that contains a nested
#PangoCFont, fill in the klass member of
the nested #PangoCFont with a pointer to
a appropriate #PangoCFontClass, then call
pango_cfont_init() on the structure.
