Add comments to specify which engines use which decoders
|Reported by:||criezy||Owned by:||sev-|
This patch add comments in the header files of the bitmap, sound and video decoders implemented in graphics/, graphics/video/ and sound/ respectively. The comments contain the list of the engines that use that decoder.
This was a suggestion from Max on the dev mailing list. I hope you like the format.
