SM4 theming documentation: what does everyone want?

[AJ 187]

With any luck, after the release of moonlight (aka dubaiOne for SM4 alpha versions), I'm going to take things a bit slower and flesh out theming documentation in order to help more people understand the theming system of the SM4 alphas.

I've already written up two tutorials on porting 3.9 (ini) and 3.95 (XML) BGAnimations to Lua:

• Ini -> Lua (3.9)
• XML -> Lua (3.95, early 4.0)

Hopefully these help people converting from one version to another, but this may not be enough, so I'm asking everyone what they want more information on. Post anything you'd like to see documented more in the theming system, even if it's a general "how do I work with x?".
