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.
It was only added to try to help DSOAL, and it's not clear if it's even
necessary. But with native EAX API support, it certainly isn't necessary
anymore.
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.
* [EAX] Fix effect GUID validation
Only NULL and REVERB was valid.
* [EAX] Fix default FX slot flags
EAX4 and EAX5 both sets to ENVIRONMENT.
* [EAX] Set default values for legacy FX slots in the initialization
* [EAX] Fix FX slot locking policy
Fail on attempt to load an effect or change a lock for EAX4 "set" call.
Unlock legacy FX slots on any EAX5 call.
* [EAX] Allow DEFER flag for "get" calls.
* [EAX] Make speaker configuration read-only
* [EAX] Initialize speaker configuration
* [EAX] Commit EAX source on a 3D source parameter call
Reference: EAX 4.0 Programmer's Guide
* [EAX] Commit EAX source on a 3D listener parameter call
Reference: EAX 4.0 Programmer's Guide
* [EAX] Commit source when it begins to play
Reference: EAX 4.0 Programmer's Guide
* Add EAX extensions (EAX 2.0-5.0, X-RAM)
* Comment out C++17 leftovers
* Remove everything related to patching
* Update alsoftrc.sample
* Rewrite integration
* Fix GCC compilation under Linux
* Always reset EAX effect properties when loading it into FX slot
MinGW-w64 generates bad code when accessing extern thread_local objects.
Wrapper functions are used to ensure it only accesses them from the same place
they're defined. This unfortunately adds a bit of overhead for what should be a
relatively simple thing.
These functions are inlined for non-MinGW targets, avoiding the overhead on
non-affected targets.
It's too unstable with larger vectors. Even when the source and listener
positions are the same, floating point precision can cause noticeable rounding
errors.
