Updated Cg-compiler to latest release, 3.1 from April 2012. This provides a
more useful package than the previous version, complete with examples and
handling distfiles for the i386 and amd64 architectures. This was originally
in pkgsrc-wip and cleaned up for pkgsrc HEAD. Resolved PR/46914 Not a

Changelog:
This is Version 1.26. Key changes in this release include:

    The argument to the --port option for the "fossil ui" and "fossil server" commands can take an IP address in addition to the port number, causing Fossil to bind to just that one IP address.
    After prompting for a password, also ask if that password should be remembered.
    Performance improvements to the diff engine.
    Fix the side-by-side diff engine to work better with multi-byte unicode text.
    Color-coding in the web-based annotation (blame) display. Fix the annotation engine so that it is no longer confused by time-warps.
    The markdown formatter is now available by default and can be used for tickets, wiki, and embedded documentation.
    Add subcommands "fossil bisect log" and "fossil bisect status" to the "fossil bisect" command, as well as other bisect enhancements.
    Enhanced defenses that prevent spiders from using excessive CPU and bandwidth.
    Consistent use of the -n or --dry-run command line options.
    Win32: Fossil now understands Cygwin paths containing one or more of the characters "*:<>?|. Those are normally forbidden in win32. This means that the win32 fossil.exe is better usable in a Cygwin environment.
    Cygwin: Fossil now understands win32 absolute paths starting with a drive letter everywhere. The default value of the "case-sensitive" setting is now FALSE, except when case-sensitivity is enabled in the Windows kernel.
    Enhancements to /timeline.rss, adding more flags for filtering results, including the ability to subscribe to changes made to individual tickets.
    Improved handling of the differences between case-sensitive and case-insensitive filesystems.
    JSON API: added the 'status' command to report local checkout status.
    Fixes to the --args support and documented this feature in the help.
    Added /stats_report page.
    Added ym=YYYY-MM filter to the "/timeline" url.
    Fixed: config reset now re-installs default ticket report format.
    ssh:// and file:// protocols now ignore proxy settings.
    Added /hash-color-test web page.
    Cherry-pick merges are recorded internally (though no yet displayed on the timeline graph.)
    Bring in the latest versions of SQLite, zlib, and autosetup from upstream.
Updated devel/fossil to 1.26
