- When GtkCompositorWidget is created, make suspended rendering state as initial one as we can't render to widget window. Enable rendering when underlying window is visible (nsWindow::ConfigureGdkWindow) or GtkCompositorWidget is assigned (nsWindow::SetCompositorWidgetDelegate). - Use moz_container_wayland_add_initial_draw_callback() at nsWindow::ConfigureGdkWindow() to set Wayland EGL window as it was before. - Make moz_container_wayland_add_initial_draw_callback() to run callbacks instantly when mozcontainer is already visible. - Implement and use moz_container_wayland_clear_initial_draw_callback() to clear mozcontainer callbacks when it becomes hidden. - Rename COMPOSITOR_PAUSED_MISSING_EGL_WINDOW to COMPOSITOR_PAUSED_MISSING_WINDOW as it's used for GLX too. - Initially pause rendering for GLX too.
