crs 16110acaa2 Added support for a global relative mouse motion option. When true
and on a secondary screen and locked to the screen (via scroll lock)
mouse motion is sent as motion deltas.  When true and scroll lock
is toggled off the mouse is warped to the secondary screen's center
so the server knows where it is.  This option is intended to support
games and other programs that repeatedly warp the mouse to the center
of the screen.  This change adds general and X11 support but not
win32.  The option name is "relativeMouseMoves".
