+ * HLE handle protocol
+ * ===================
+ *
+ * To avoid needing HLE services to keep a separate handle table, or having to directly modify the

+ * will decode the incoming handles into object pointers and insert a id in the buffer where the
+ * handle would normally be. The service then calls GetIncomingHandle() with that id to get the
+ * pointer to the object. Similarly, instead of inserting a handle into the command buffer, the
+ * service calls AddOutgoingHandle() and stores the returned id where the handle would normally go.
+ *
+ * The end result is similar to just giving services their own real handle tables, but since these
+ * ids are local to a specific context, it avoids requiring services to manage handles for objects
+ * across multiple calls and ensuring that unneeded handles are cleaned up.
