Actually what Wine's doing is buffering all src data, then decoding however
much it can from that buffer, and leaves the rest until the next call. So you
do increment the source data by the amount "used". The difference is that Wine
leaves the extra source data buffered for the next call, whereas Windows leaves
it unbuffered and reports it unused.

Of course, Wine's method can cause some problems to unsuspecting apps. Namely
that the buffered input will continue to grow as long as there's not enough
output to decode it all. If you attempt to continue buffering 0 src bytes until
you get 0 dst bytes, you'll get everything.. but I suppose this should be fixed
to match Windows' behavior.
