[General] Good News: Canvas Port

Folks -

We have just put together a port of The Lively Kernel that uses the  
Canvas graphics API instead of SVG.  This means potentially better  
browser support and potentially better performance, though neither is  
the case yet.  We hope you will enjoy helping us to debug this port.   
You can find it at...


... but you need to be running the latest WebKit or MineField, or  
possibly Chrome or Safari 4 beta.

Almost all the graphics works at this point, but there is one  
remaining hole in the implementation.  Up to now, we have been using  
the serialization support in the SVG DOM to save Lively state on web  
pages.  In order to save our state without this SVG support, it will  
be necessary to add a serialization / deserialization package that  
uses another mechanism such as, eg, JSON.  This could be a lot of fun  
for one of our braver community members (ahem).

Try it out.

Tell us about problems.

... and have fun!
