Grabbing screen shots (but not to file)

Once I have the (630x480) buffer, I can always run it through libz or something to get out a compressed string, then unpack it on the other end of the socket I'll post it on. Plus, 20-30 Hz will probably be good enough to get a sense of what the agent sees (to compare with the metrical and symbolic maps that our research software creates---using the "virtual robot sensors" I built for the Vizard agent).

That would be extrememly helpful. I am not familiar with programming in Windows (in fact the machine I'm using doesn't even have Visual Studio), so unless its something I could do in python with minimal knowledge of Vizard or OpenGL, it would be best to have someone else write this for me.

Unfortunately, I'm running Vizard 2.53g. Is that a deal breaker? Regardless, I'll contact support to beta test v3.0, but I'll have to ask my employer about his plans to upgrade our Vizard purchase an upgrade to v3 when it comes out. Let me know.
