+ * BUGS: The wrapper really should maintain one symbol table per port. This
+ * could possibly be impemented, To do that, the port-independent symbols need to be lifted out,
+ * and one would have to create a number of mapping tables:
+ *
+ * port -> symbol table
+ * context -> port
+ * surface -> port
+ * subpicture -> port
+ *
+ * and reference the right table when needed.
+ * This needs to be done only if there is a player that wants to access two displays with different
+ * hardware simultaneously. Not likely as of today.
