44 * This function is called when i3 is initialized, because with some login
45 * managers, the root window will not have a cursor otherwise.
47 * We have a separate xcursor function to use the same X11 connection as the
48 * xcursor_load_cursors() function. If we mix the Xlib and the XCB connection,
49 * races might occur (even though we flush the Xlib connection).
