On the topic of tracking with non-windowed cairo objects, and zoomable

Here is a design document describing the ScriptX Tracking Service that I
developed at Kaielda, to solve some of these problems inherent with
efficiently delivering events to graphical (non-windowed) objects,
through a series of transformations (and offscreen buffers).
This looks pretty cool - thanks Don!
I've implemented a lot of this functionality but to put it bluntly it's
been crying out for a refactor - I particularly like the way you're
decoupling the event coord transforms - this is something that has been
causing me particular pain as I've tried to scale up my object model.
