void pango_font_description_set_variations_static ( PangoFontDescription* desc, const char* variations )
Sets the variations field of a font description.
This is like
that no copy of
variations is made. The caller must make sure that
the string passed in stays around until
desc has been freed
or the name is set again. This function can be used if
variations is a static string such as a C string literal,
desc is only needed temporarily.
