Detailed Description

CAUGuiMeter - representing private values (internal parameters).

This class is merely a helper class for general visualizaion purpose like VU meters.

It is currently bound to represent values from normalized float values that are obtained from an Array of floats that's passed from the process class to the GUI via GetProperty() with a PropertyID defined kInternalParameterProperyID (the one that Apple reserves 0-63999 for their own purpose, so this is 64000).

It could however be extended to use non-propagated AU Parameters as well, as this is the recommended "new way to go" of passing private data from process to GUI. But that would better be handled by Displays where this functionality is already in. One only has to conditionally disable mousing in Displays for that.

If it turns out this class is somewhat useless, it will be deprecated in one of the next updates to CAUGui...

Due to not being bound to AU Parameters, CAUGuiMeters update on timer driven basis when the parameter has changed
