Set a flag on the pointer-emulating touch event

Toolkits need to know which touch event emulated a pointer event and which
ones do not. To quote Carlos Garnacho:

    GTK+ does client-side windows by default (GdkWindows without a backing X
    window), for this to work the toplevel window in the client needs to
    select for more events that it wouldn't normally select for in order to
    cater for the event masks in such child "windows". This means that
    ideally GTK+ should set the touch events mask in the toplevel, and then
    find out whether the "window" would receive pointer or touch events for
    the sequence emulating the pointer, and perform the emulation itself.
