<pre>While testing the Wayland backend for SDL2 I noticed a repeatable problem with
the user data pointer passed back to the pointer listeners.
When the mouse enters the application, the corresponding callback is fired
(pointer_handle_enter in our case), but the first parameter is invalid (it
seems to be consistently 0xffffffffc). The rest of the parameters seem sane.
This error does not happen with Wayland/Weston 1.3, but it is present in 1.3.91
and the latest from git.
The invalid pointer eventually produces a segfault.</pre>
