Source's oclussion and exclusion properties should be taken into account only for listener's environment (see p. 16, p. 56, pp. 62-63 and p. 64 of "EAX® 4.0 Programmer’s Guide").
Even though it's only a single value, this allows for not having to explicitly
track version changes, since the version being changed to will always have a
property change, implicitly marking an EAX update/commit for the source.
Based on DirectSound's EAX behavior, committing any EAX property commits *all*
deferred property changes, not just the object being changed. So applying EAX
changes can be handled in one place.
I'll assume for now that the limits for the EAX properties will keep the filter
gain from getting out of hand. The filter's gainhf is relative to the gain and
is limited to 0dB max.
The symbol only exists for compatibility due to it having been erroneously
exported in previous versions (even though it shouldn't have been used
directly, some apps could have).
