Azaezel fbfd3ed8ed clang: constructor initialization order 
while not a major issue per-se, the sheer number of times the engine has to jump back in memory and backfill data in a given class can add up. First run of... many.,

"@brief An invisible 3D object that emits sound.\n\n"
"Sound emitters are used to place sounds in the level. They are full 3D objects with their own position and orientation and "
"when assigned 3D sounds, the transform and velocity of the sound emitter object will be applied to the 3D sound.\n\n"
"Sound emitters can be set up of in either of two ways:\n"
"<ul>\n"
"<li><p>By assigning an existing SFXTrack to the emitter's #track property.</p>\n"
"<p>In this case the general sound setup (3D, streaming, looping, etc.) will be taken from #track. However, the emitter's "
"own properties will still override their corresponding properties in the #track's SFXDescription.</p></li>\n"
"<li><p>By directly assigning a sound file to the emitter's #fileName property.</p>\n"
"<p>In this case, the sound file will be set up for playback according to the properties defined on the emitter.</p>\n"
"</ul>\n\n"
"Using #playOnAdd emitters can be configured to start playing immediately when they are added to the system (e.g. when the level "
"objects are loaded from the mission file).\n\n"
"@note A sound emitter need not necessarily emit a 3D sound. Instead, sound emitters may also be used to play "
"non-positional sounds. For placing background audio to a level, however, it is usually easier to use LevelInfo::soundAmbience.\n\n"
"@section SFXEmitter_networking Sound Emitters and Networking\n\n"
"It is important to be aware of the fact that sounds will only play client-side whereas SFXEmitter objects are server-side "
"entities. This means that a server-side object has no connection to the actual sound playing on the client. It is thus "
"not possible for the server-object to perform queries about playback status and other source-related properties as these "
"may in fact differ from client to client.\n\n"
