Since the resource is released just after (and therefore terminated).

Release() (instead of Terminate()) from the closing thread. Don't hold twice
the ref count for private resources.

This will not change anything when the resource is provided to the
input_thread_t. The Release() call will just decrement the ref count.

This will also not change anything when the input_thread_t create its own
resource. The Release() will actually terminate the resource like before, and
from the closing thread.

Since var_GetBool() is way longuer to process.

callback lost or disabled ?

Now that there is more than 2 possible modes (regular playback,
preparsing, thumbnailing) it makes more sense to check for an explicit
match.

- Multiple thumbnail can now be used
- Discovery, thumbnailing & metadata extractions are now interruptible
- An entry_point_added event has been added

Since we soon will need something else than int64

The clear/begin/end scene is always done on our local IDirect3DDevice9. No need
to force the host to do it a second time.

It's simpler on the host side and we don't need to be tied to the HWND it would
use internally.
