18511f851e Put duplicate code of a-comp and a-expander into one file ...
... for better maintainability

consolidated duplicate code:
  * drawing the dB-grid of a-comp's and a-expander's full display
  * drawing the gain reduction bar of a-comp's and a-expander's full display
  * the entire only-bars display

0c64eacef5 Consolidated a-comp/a-exp run_mono() and run_stereo() to one run()
Up to now we had in a-comp and a-exp one run_mono() and one run_stero()
function which where almost identical except that run_stereo() treated two
in/outs and run_mono() only one. Now we store the number of channels
acomp->n_channels according to the URI and in run() we loop over an array of
pointers to the in/out buffers.

46aa204eb8 Limit gain reduction of a-expander to 160 dB in order to ...
improve release behavior.

This slows down the release after events like single snare hits as, the gain
reduction only releases to 160 dB rather than to inf.

2a5d56215c New visualization of the compressor state in graph view
To properly visualize attack and release we calculate the input level out of
the gain reduction the output level threshold and ratio.

if (output_level >= threshold) { // no expansion
        input_level = output_level
} else {
        input_level = (gain_reduction - threshold * (1-ratio)) / ratio
}
