flags passed from convert func

for async driver queueing

dwDriver: DWORD;

driver instance flags

fdwPrepared: DWORD;

driver instance data

all remaining fields are used by the ACM for bookkeeping purposes. an ACM driver should never use these fields (though than can be helpful for debugging)–note that the meaning of these fields may change, so do NOT rely on them in shipping code.
