// When the 3Dconnexion driver is running the system gets, by default, mouse wheel events when rotations around the X axis are detected.
// We want to filter these out because we are getting the data directly from the device, bypassing the driver, and those mouse wheel events interfere
// by triggering unwanted zoom in/out of the scene
// The following variable is used to count the potential mouse wheel events triggered and is updated by:
// Mouse3DController::collect_input() through the call to the append_rotation() method
// GLCanvas3D::on_mouse_wheel() through the call to the process_mouse_wheel() method
// GLCanvas3D::on_idle() through the call to the apply() method
