+Subject: [PATCH 16/16] Allow multiple wayland compositor state data per
+ process
+
+When eglBindWaylandDisplayWL is called store the wl_global
+created in a list associated with the wayland display.
+This allows multiple wayland compositor instances to be
+created and used per process. This scenario is common for
+applications integrating externl process UI elements
+via embedded composition e.g. westeros
