Re: [web-audio-api] Specify what should happen when passing invalid offset/duration values to AudioBufferSourceNode.start (#18)

I don't think throwing an exception is necessary here.

I don't like the behavior of just ignoring the offset if it's >= the length of the buffer. That creates a discontinuity as the offset increases from before the buffer end to after it.

If compatibility issues don't trump, then I suggest first clamping the offset to [0, length], then adding the duration to find the endpoint and clamping the endpoint.
