Dominique Martinet ec51a219a7 glfw x11: update cursor position on enter event 
kitty would have an incorrect position when clicking after changing window
without moving (e.g. change workspace, create new kitty etc)

For new kitty window, initial position would be 0 and selection paste would
not work because of this
