Enhanced vic AG port to Mac

[edit] Outcome

Ask Prof. Reichelmeyer about making this available to Mac-using SE students

VicR Binaries & SVN info
- The AG service wrappers there partially work. For proper operation, they depend on some AG toolkit changes which are expected for the AG3.1 release.
The best way to start is probably to figure out your preferred building mechanism, using the current OSX vic. method is shown here.
When mailing about this, CC: to Leon and Doug as well as Chris Willing.
After SVN checkout, look at the READMEs (in ag-media and vic directories) from which you'll get ideas about the issues we've been addressing. There are also some UML diagrams which show the new classes involved and how everything fits together.
In more general terms, what will be needed is a renderer and a grabber; all the other stuff. [sic; is done?]
Let us know how you go - getting started is usually the hardest part, so don't hesitate to ask if you have problems or questions.
For the DV/HDV vic, Leon modified Tcl/Tk to add a more accurate timer (I think similar to what the Tcl/Tk 2.5 betas use). For the Mac DV/HDV port, if Tcl/Tk might need to be built from source code and statically linking against vic (like on other platforms), fixing the runtime Tcl/Tk error may or may not be an issue still. I suspect it is due to some Tcl package (possibly involving the Mac menubar) not being bundled with ActiveTcl.
Leon's Tcl/Tk 8.0 mods would need to be added to Tcl/Tk 8.4...
- we could probably move the existing code base at some stage to use Tcl/Tk 8.4 also.
