GAP aware and passthrough are two different properties but passthrough implies
GAP aware (not the other way around).

A passthrough element will never (and can't) change the content of the buffers,
i.e. the output buffers will still contain silence if the GAP flag was set and
there's no reason to unset it.

The reason why the GAP aware mode exists is only to make sure that the output
buffers only contain the GAP flag if the elements make sure that the buffers
only have a GAP flag if they really contain silence. For a passthrough element
this is always true and if the element understands the GAP flag or not doesn't
matter, a buffer with GAP flag must contain silence.
