Weston 1.9 crashes on touchscreen input

When I touch the edges of the screen, Weston crashes.

Refer to https://www.mail-archive.com/wayland-devel@lists.freedesktop.org/msg29102.html - it notes that it was fixed in 1.10 and links to this commit which fixes it: https://cgit.freedesktop.org/wayland/weston/commit/src/input.c?id=2c40d1d30eabe46706822a8b5c94579aeba58e84

My quick and dirty hack job of a fix was as follows:

Make the corresponding edits to src/input.c in function default_grab_touch_down

Then

followed by reloading the SD card image. Now I can touch the edges all I want and no crash

I don't know what's the cleaner way to fix this, maybe the trick is to just use a newer version of Weston if that's easy enough?
