Audio-ISSUE-76 (BiquadFilterNode): BiquadFilterNode is underdefined [Web Audio API]

The filter operation is undefined, with wording such as "standard second-order resonant lowpass filter with 12dB/octave rolloff." A lot more specificity is required.

Wikipedia is the reference for several of the filter modes. We could not find any mode that is implementable given the information provided.
