[PATCH 2/4] quartz/filtergraph: Count renderers in IMediaControl::Run.

[Zebediah Figura]

This patch breaks the qcap:filewriter test:

../../../../wine/tools/runtest -q -P wine -T ../../.. -M qcap.dll -p
qcap_test.exe filewriter && touch filewriter.ok

I suspect you want to count in Pause rather than Run.

This too could probably be a comment in the code, though if there's a
comment in update_seeking I guess it's less important.
