AcceleratedBatchedMeshRaycast: use getVisibleAt instead of drawInfo object

[agargaro]

Two questions:

1. It's necessary to create a way to get instances in use count (drawInfo.length). Is an instancesCount getter okay?

2. The method getVisibleAt and property instancesCount (and other future methods) , may not exist if the user is using an older version of three.js. How would you prefer to proceed?

Adding these methods to BatchedMesh.prototype?
Change the minimum version of three.js?

I think adding a getter for instanceCount and geometryCount would be good additions to BatchedMesh.

The method getVisibleAt and property instancesCount (and other future methods) , may not exist if the user is using an older version of three.js. How would you prefer to proceed?

We can handle that once they're available. But we can possibly check the version again or wait and then release a new major revision after a few releases, I think.

Thanks! I made issue #707 to track the addition of other functions to BatchedMesh.
