 *
 * Some versions of XAudio2 add or remove functions to the COM vtables, or
 * incompatibly change structures. This file provides implementations of the
 * older XAudio2 versions onto the new XAudio2 APIs.
 *
 * Below is a list of significant changes to the main XAudio2 interfaces and
 * API. There may be further changes to effects and other parts that Wine
 * doesn't currently implement.
 *

 *   Change struct XAUDIO2_PERFORMANCE_DATA
 *   Change IXAudio2Voice::GetOutputMatrix return value to void
 *   Add parameter to IXAudio2VoiceCallback::OnVoiceProcessingPassStart
 *   Change struct XAPO_REGISTRATION_PROPERTIES. CAREFUL when using! Not all
 *       implementations of IXAPO are Wine implementations.
 *
 * 2.2
 *   Change CLSID_XAudio2
 *   No ABI break
 *
 * 2.3
 *   Change CLSID_XAudio2
 *   ABI break:
 *     Change struct XAUDIO2_PERFORMANCE_DATA
 *
 * 2.4
 *   Change CLSID_XAudio2
 *   ABI break:
 *     Add IXAudio2Voice::SetOutputFilterParameters
 *     Add IXAudio2Voice::GetOutputFilterParameters
 *     Add IXAudio2SourceVoice::SetSourceSampleRate

 *
 * 2.5
 *   Change CLSID_XAudio2
 *   No ABI break
 *
 * 2.6
 *   Change CLSID_XAudio2
 *   No ABI break
 *
 * 2.7
 *   Change CLSID_XAudio2
 *   No ABI break
 *
 * 2.8
 *   Remove CLSID_XAudio2
 *   Change IID_IXAudio2
 *   Add xaudio2_8.XAudio2Create
 *   ABI break:
 *     Remove IXAudio2::GetDeviceCount
 *     Remove IXAudio2::GetDeviceDetails
 *     Remove IXAudio2::Initialize
