/*!	\class  InputDevice  inputdevice.h  "synfigapp/inputdevice.h"
**	\brief  This class provides a device independent representation the state
**	        of an input device.
**  \see  studio::DeviceTracker
**  \see  synfigapp::Settings
**
**   The representation includes both the GDK state (e.g., mode) and synfigstudio
**   state (e.g., outline color). An object of this class can be saved and
**   restored using its Settings object, provided by the settings method.
