Functions
QVector< int >	OpenSWMM::Render::sampledFrameIndices (int frameCount, double sampleRate)
	Indices of the frames the sampler would pick, for the same frameCount and sampleRate. Pure function — useful for tests and for showing the user which frames were sampled. Returns an empty vector when frameCount == 0.
QVector< double >	OpenSWMM::Render::sampleBreaksAcrossFrames (const IntervalBinner &binner, const QVector< QVector< double > > &perFrameValues, double sampleRate=0.2)
	Pick perFrameValues at sampleRate fraction (≥ 1 frame), flatten the selected frames' values, and call IntervalBinner::computeBreaks() on the flat sample.
