Comment (by devans@…):

 Proposed patch attached that
    * provides update to version 2.40.1
    * updates dependencies (see configure.in for confirmation) (gtk3 used
 for utility rsvg-view-3)
    * updates configuration to enable introspection (now explicitly
 required) and vala support for dependents that may require it.
    * removes outdated patch-configure.diff
    * adds new upstream patch which addresses build failure due to use of
 canonicalize_file_name() (portability issues).

 Note that I have done only minimal testing of this version but the
 utilities work correctly and gimp2, which uses the library to open svg
 files, works as well.  This version is ABI compatible with the previous
 one so no rev bumps of dependents required.

 Hope this is helpful
