Add org.gnome.Mutter.RemoteDesktop hint to turn off animations
xsettings/gsd-xsettings/gsd-remote-display-manager.c
in gnome-settings-daemon turns off animations when vino is active. What we probably want to replace this with is letting e.g. gnome-remote-desktop ask to turn off animations instead. To do that, we need to add a way for it to provide such a hint.
Said hint needs to be communicated to gnome-shell in some way, probably via MetaRemoteAccessController
, MetaRemoteAccessHandle
or something.
