Deprecated enum PangoDirection is used in non-deprecated functions

All of the pango-bidi-type.h file, including the declaration of PangoDirection has been deprecated and surrounded by #ifndef PANGO_DISABLE_DEPRECATED/#endif. But some non-deprecated functions in pango-context.h and pango.utils.h have parameters of type PangoDirection. This causes error messages, such as

/opt/gnome/include/pango-1.0/pango/pango-context.h:93:14: error: ‘PangoDirection’ has not been declared

when I try to build pangomm with PANGO_DISABLE_DEPRECATED defined.
