/* MiscVirtual3DMouseFrontend.m				 
 *
 * This object deals with the GUI we need to do all the settings.
 * It is the frontend to the slider or trackPad based 3DMouse system.
 * Basically intended for testing a custom app without owning a real 3Dmouse.
 *
 * For interface-info see the header file. The comments in this file mostly
 * cover only the real implementation details.
