will write the latest mouse deltas and button states into the structure. Returns 1.
Mouse_Load() loads the mouse driver up on a free Propeller core. If the driver is already loaded this
Mouse_Unload() unloads the mouse driver freeing a core on the Propeller. Typically, you will do this
Mouse_Read(…) reads the current mouse event from the driver. In this case, it only reads “relative”
