[RFC wayland] protocol: Add high-resolution wl_touch timestamp event

2017-11-21 Thread Alexandros Frantzis
wl_touch events currently use a 32-bit timestamp with millisecond resolution. In some cases, notably latency measurements, this resolution is too coarse-grained to be useful. This protocol update adds a wl_touch.timestamp event, which is emitted just before an up, motion or down touch event. The t
