	HD_DECLARE_DATASOURCE_ABSTRACT (HdSampledDataSource)
virtual VtValue	GetValue (Time shutterOffset)=0
	Returns the value of this data source at frame-relative time shutterOffset.
virtual bool	GetContributingSampleTimesForInterval (Time startTime, Time endTime, std::vector< Time > *outSampleTimes)=0
	Given a shutter window of interest (startTime and endTime relative to the current frame), return a list of sample times for the caller to query with GetValue such that the caller can reconstruct the signal over the shutter window.
