[Bug:  the property on canvas is called `capabilities` not  
`features`.  Error on my part.]

The point of canvas.features is to _not_ have to stay with the lowest  
common denominator.  It allows us to gracefully add features and warn  
on platforms that are not supported, and it allows the LZX developer a  
way to decide how to deal with unsupported features in their  
application.

As a simple example, consider `lz.Audio.playSound`.  Right now  
`canvas.capabilities.audio` is false for DHTML and will give a debug  
warning if you call `playSound` on DHTML, but we could improve that to  
use HTML 5 audio when the platform supports it.  Since this is a  
pretty straight-forward extension of an existing API, maybe that is a  
good place to start experimenting?
