 558          * Why do we need two roundtrips here?
 559          *
 560          * wl_display_get_registry() sends a request to the server, to which
 561          * the server replies by emitting the wl_registry.global events.
 562          * The first wl_display_roundtrip() sends wl_display.sync. The server
 563          * first processes the wl_display.get_registry which includes sending
 564          * the global events, and then processes the sync. Therefore when the
 565          * sync (roundtrip) returns, we are guaranteed to have received and
 566          * processed all the global events.
 567          *
 568          * While we are inside the first wl_display_roundtrip(), incoming
 569          * events are dispatched, which causes registry_handle_global() to
 570          * be called for each global. One of these globals is wl_shm.
 571          * registry_handle_global() sends wl_registry.bind request for the
 572          * wl_shm global. However, wl_registry.bind request is sent after
 573          * the first wl_display.sync, so the reply to the sync comes before
 574          * the initial events of the wl_shm object.
 575          *
 576          * The initial events that get sent as a reply to binding to wl_shm
 577          * include wl_shm.format. These tell us which pixel formats are
 578          * supported, and we need them before we can create buffers. They
 579          * don't change at runtime, so we receive them as part of init.
 580          *
 581          * When the reply to the first sync comes, the server may or may not
 582          * have sent the initial wl_shm events. Therefore we need the second
 583          * wl_display_roundtrip() call here.
 584          *
 585          * The server processes the wl_registry.bind for wl_shm first, and
 586          * the second wl_display.sync next. During our second call to
 587          * wl_display_roundtrip() the initial wl_shm events are received and
 588          * processed. Finally, when the reply to the second wl_display.sync
 589          * arrives, it guarantees we have processed all wl_shm initial events.
 590          *
 591          * This sequence contains two examples on how wl_display_roundtrip()
 592          * can be used to guarantee, that all reply events to a request
 593          * have been received and processed. This is a general Wayland
 594          * technique.
