This function will capture a single device independent bitmap.
If the method succeeds, the caller must free the returned HDIB by calling the GlobalFree function.
Note: The frame data is retrieved from the underlying graph after the processing
filters. If the capture needs to occur before the processing is completed
use the LeadVideoCallBackFilter and place it first in the collection of
processing filters.
