    Hash : 9174b011
    Message : Update to pixman 0.18.4. Tweak build to use libpthread-stubs for TLS emulation instead of forcing every application using pixman to use -pthread. Tested by jasper@ and landry@ on a bulk ports build.

    #   Pixman versioning scheme
    #
    #   - The version in git has an odd MICRO version number
    #
    #   - Released versions both development and stable have an even MICRO 
    #     version number
    #
    #   - Released development versions have an odd MINOR number
    #
    #   - Released stable versions have an even MINOR number
    #
    #   - Versions that break ABI must have a new MAJOR number
    #
    #   - If you break the ABI, then at least this must be done:
    #
    #        - increment MAJOR
    #
    #        - In the first development release where you break ABI, find
    #          all instances of "pixman-n" and change them to pixman-(n+1)
    #
    #          This needs to be done at least in 
    #                    configure.ac
    #                    all Makefile.am's
    #                    pixman-n.pc.in
    #
    #      This ensures that binary incompatible versions can be installed
    #      in parallel.  See http://www106.pair.com/rhp/parallel.html for
    #      more information
