Thanks! I'm glad there's interest!

I think you hit the nail on the head.

To me, I think this effort will be most effective if it focuses on a 
cohesive set of methods that either make complex operations easier or 
significantly faster, or make nigh-impossible things possible.

As you say, a geometry API could do any number of things, but in the 
end, it should just be supplemental to the code authors will have to 
write anyway, just as the JS Math object gives basic math primitives.

In the Web Audio WG, we had good success with establishing what we 
wanted it to accomplish by laying out our use cases, and deriving 
requirements from that; we started with all the use cases we could think 
of that might be useful, then discussed their relative priority; for 
medium or high priority items, we wrote requirements that covered them. 
The more (and higher-priority) use cases that a particular requirement 
met, the more important we decided it was.

I took the liberty of starting a Use Cases and Requirements page [1], 
based on the format we used for the Web Audio API.

I also agree that we should make an effort to be disciplined in what we 
decide are priorities, because we need to make something that browsers 
will actually implement and ship! And that same discipline will help us 
focus and get something done in a reasonable time frame.
