The volume element has a maximum gain of 10 which is overly restrictive

In gstvolume.c we have the following.

#define VOLUME_MAX_DOUBLE            10.0

  g_object_class_install_property (gobject_class, PROP_VOLUME,
      g_param_spec_double ("volume", "Volume", "volume factor, 1.0=100%",
          0.0, VOLUME_MAX_DOUBLE, DEFAULT_PROP_VOLUME,
          G_PARAM_READWRITE | GST_PARAM_CONTROLLABLE | G_PARAM_STATIC_STRINGS));

So we can only scale an audio waveform by a factor of 10, no more. This is overly restrictive, especially considering the fact that the audio signals can have some large bit depths (even floating point) which implies a huge amount of dynamic range (for plenty of headroom).

Do we need to have a maximum value? Perhaps we should just set it to positive infinity (1.0/0.0) and let the user decide what a reasonable value is.
