Update the multi-reverb example with improved transitions

This better calculates the environment coverage by correctly calculating the
portal's extents, improves the panning direction when close to the portal, and
applies attenuation based on contribution. Movement has changed to make the
listener move back and forth between environments with a stationary source,
rather than continually looping environments with a position-relative source.
