The wp_pointer_constraints protocol is a protocol which enables clients to manipulate the behavior of the pointer cursor associated with a seat. Currently available constraints are locking the pointer to a static position, and confining the pointer to a given region. Currently locking is fully implemented, and confining is implemented for rectangular confinement regions. What else is lacking is less troublesome semantics for enabling the lock or confinement; currently the only requirement implemented is that the window that appears focused is the one that may aquire the lock. This means that a pointer could be 'stolen' by creating a new window that receives active focus, or when using focus-follows-mouse, a pointer passes a window that has requested a lock. This semantics can be changed and the protocol itself allows any semantics as seems fit. https://bugzilla.gnome.org/show_bug.cgi?id=744104
