disable_hardware_cursor - Disables the OS hardware cursor. Allegro game programming library.

       After  calling  this  function,  Allegro will be responsible for drawing the mouse cursor rather than the
       operating system.  On  some  platforms  calling  enable_hardware_cursor()  makes  the  return  values  of
       get_mouse_mickeys() unreliable. After calling this function, get_mouse_mickeys() returns reliable results
       again.
