public void set_variations_static (string variations)
Sets the variations field of a font description.
This is like [method@Pango.FontDescription.set_variations], except that no copy of
variations is made. The caller must make sure
that the string passed in stays around until this 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, or if this is only needed
a string representing the variations
