Subject: [pango] Add a header for versioning macros
Date: Wed, 29 Jun 2016 09:33:56 +0000 (UTC)
commit 57964efb280369db2731bfc070f3e73c9a860d18
Author: Chun-wei Fan <fanchunwei src gnome org>
Date:   Mon Jun 6 23:35:40 2016 +0800

    Add a header for versioning macros
    
    This header is used for:
    -Indicating what stable versions an API is introduced at and after 1.30.0.
    -Indicating what APIs are deprecated, and which stable release series
     they are deprecated if the deprecation is done after 1.30.0.  This replaces
     the use of G_DEPRECATED* in Pango.
    -Use in a later commit to be used to export symbols directly via compiler
     directives instead of doing so over .def files, for compilers that do not
     support exporting via regex expressions.
