This is a request to expose pitch adjustment in Bodge/Gamekit. I was imagining doing something like this in Gamekit:

(gamekit:play-sound :foo :pitch 0.5)

Which would play the :foo sound at half pitch, for example.

While I'm asking, it would also be nice to be able to adjust the volume of sounds as well (looks like OpenAL refers to it as AL_GAIN).

Thank you! :)
