Font support with font data provided by the user
<!-- ##### SECTION Long_Description ##### -->
<para>
The user-font feature allows the cairo user to provide drawings for glyphs
in a font. This is most useful in implementing fonts in non-standard
formats, like SVG fonts and Flash fonts, but can also be used by games and
other application to draw "funky" fonts.

<!-- ##### SECTION Stability_Level ##### -->
<!-- ##### MACRO CAIRO_HAS_USER_FONT ##### -->
<para>
Defined if the user font backend is available.
This macro can be used to conditionally compile backend-specific code.
The user font backend is always built in versions of cairo that support
this feature (1.8 and later).
