Original commit message from CVS: * gst/equalizer/gstiirequalizer.c: (gst_iir_equalizer_band_set_property), (gst_iir_equalizer_child_proxy_get_child_by_index), (gst_iir_equalizer_child_proxy_get_children_count), (gst_iir_equalizer_child_proxy_interface_init), (gst_iir_equalizer_class_init), (arg_to_scale), (setup_filter), (gst_iir_equalizer_compute_frequencies): * gst/equalizer/gstiirequalizer10bands.c: (gst_iir_equalizer_10bands_class_init): * gst/equalizer/gstiirequalizer3bands.c: (gst_iir_equalizer_3bands_class_init): * gst/equalizer/gstiirequalizernbands.c: Better algorith for the center frequencies. Subtract band filters from input for negative gains. Rework the gain mapping.
