rlm@0: * a device has a two names, 
rlm@0:  - *name*,    which is the filename and which appears before all of the functions.
rlm@0:  - *trueName*, which is a string that is used to summon the device.
rlm@0: 
rlm@0: 
rlm@0: Every device has the *<name>_data* struct, which is where all the
rlm@0: device specific state is located.
rlm@0: 
rlm@0: In the function *<name>_open_playback*, the device is initialized,
rlm@0: here the trueName is set, and the devices data is initialized.
rlm@0: 
rlm@0: The ALCdevice's ExtraData field must always be cast to to the actual
rlm@0: data struct that the device uses.
rlm@0: 
rlm@0: 
rlm@0: 
rlm@0: the =open_playback= function is where everything is initialized,
rlm@0: 
rlm@0: 
rlm@0: but the =reset_playback= is where the actual thread which is the heart
rlm@0: of the device is started.
rlm@0: 
rlm@0: 
rlm@0: every device has a <name>Proc function which takes a pointer to an
rlm@0: ALCdevice and is run in a separate thread.  It is this procedure that
rlm@0: actually does stuff with sound data.
rlm@0: 
rlm@0: 
rlm@0: It is the ALContext which controls the particulars of a listener.
rlm@0: 
rlm@0: The context contains the device.
rlm@0: 
rlm@0: * so do we need a new context for each listener, alone with their own
rlm@0: devices?
rlm@0: 
rlm@0: However, the device also maintains a *list* of contexts...
