Change the audio filters to use a double instead of rationals for the
ratio of output to input size. The rationals could overflow when
calculating the overall ratio of a filter chain and gave no real
advantage compared to doubles.

- a passive locking mechanism to enable the matrix to switch between active
and passive mode, which enhances the stereo image.
- a center front cancellation algorithm that damps the cross-talk if the
sound is coming predominantly from center (e.g. if there is dialogue).
These two new features should enhance the quality of surround downmix
noticeably.
Also a correction to the active gain control is included. The previous
implementation of Lt + Rt/Lt - Rt AGC should be fine in most cases, but the
calculation was inconsistent (gain unitarity is not guaranteed to be
preserved).

- Bass compensation gain corrected (which was set too low), now the
sound should be even more transparent
- A (unified) dual axes active matrix decoder with adaptive steering
- capable of decoding matrix surround encoded inputs, with stereo rear
- capable of decoding matrix encoded rear center
- Purely stereo mixing without unneccessary rear filter calculations
- The decoding structure message is moved, because at the old place it
gave incorrect messages.
