release events when pointer is outside window as well as re-enabling keyrepeat. * clutter/glx/clutter-stage-glx.c: (clutter_stage_glx_realize): select for KeyPressMask and KeyReleaseMask even with XInput enabled. * clutter/x11/clutter-backend-x11.c: (_clutter_x11_register_xinput): Disabled the XInput keyboard code paths (comments and #if 0's) * clutter/x11/clutter-event-x11.c: (event_translate): always handle keyboard events without regard to XInput.
