It has the same focus, but adds the functionality of sending relative pointer motions unhindered by constraints such as monitor edges or other barriers. It also contains unaccelerated pointer motion information. Signed-off-by: Jonas Ã…dahl <<a href="mailto:jadahl@gmail.com">jadahl@gmail.com</a>> --- There has alreay been RBs on this protocol, but I'd like to get them explicitly re-RB:ed considering that the protocol has changed some, even though the changes have not been major ones. Changes since the last version sent as weston patches: Interfaces and protocol renamed according to wayland-protocols naming conventions. Accelerated and unaccelerated motion deltas have the data type wl_fixed_t now again. 64 bit fixed point deltas was deemed unnecessary, and wl_double_fixed_t was dropped. 64 bit timestamp argument name suffix changed from msb/lsb to hi/lo. Various other minor changes.
