Graphics libraries and scripting

In case you're interested, in addition to adding Lua-based scripting to noatikl, I've been using the same scripting engine in prototyping optikl, the generative visual art program we hope to release some time.

To help optikl and our other products go wherever we want, including maybe to mobile, I've written a common graphics library adaptor layer that sits on top of SDL, Juce and what have you. So this will let us, in future, write our apps once and simply recompiling them for whatever the target platform might be, without the need for any major rewrites. :)
