Common class for instruments that use a custom SVG for a circular gauge. This SVG has been specifically made to easily accommodate large changes in the SVG to be able to support a wide variety of instruments. All classes that begin with TRSCircularXXX or TRSRotaryXXX descend from this class and use the same SVG resource.
The base class for the IMPACT Multimedia Instrument package add-on. It defines properties, events, and methods common to all instruments in the package.
