Doppler support in the code was a bit fiddly when I looked at it - due  
to different implementation have missing or incomplete doppler  
support, and hence us falling back to a software routine instead of  
always letting OpenAL deal with Doppler :(

So, it's entirely possible for an OpenAL implementation to not support  
doppler, sadly.

Incidentally, one of the many, many things on my 'if I ever have time'  
list is to clean up the OpenAL driver code in the main loop to support  
multiple positioned sources - the current code assumes all positioned  
sounds originate from the main aircraft, which is obviously not ideal  
(though equally, a good tradeoff to get things going). The good test  
for this would be dog-fighting fly-bys in multi-player - as I  
understand it, right now, the doppler-shift on engine sounds from MP  
aircraft will be completely wrong. This is only based on encountering  
the code while reading the main loop code - perhaps I'm completely  
mistaken about this.
