Touch support on wayland

Hi list.

I am using weston + SDL2 (from hg)

The problem is that my application does not receive touchscreen events
(other weston apps receive touch events).

I’ve added a printf to SDL_waylandvideo.c : display_handle_global()
hoping that i would get
interface="qt_touch_extension"
that would call Wayland_touch_create but it doesn’t receive that.

Is my assumption correct that sdl2 needs some qt compositor for touch
to work (under wayland)?

Thank you.–
With best regards,
Dmitry
