xwayland: Delay cursor visibility update

Olivier Fourdan requested to merge ofourdan/xserver:xwayland-warp-newly-visible-cursor into master

Xwayland won't emulate XWarpPointer requests if the cursor is visible, this is to avoid having the cursor jumping on screen and preventing random X11 clients from controlling the pointer in Wayland, while allowing games which use that mechanism with a hidden cursor to work in Xwayland.

There are, however, games which tend to do it in the wrong order, i.e. show the cursor before moving the pointer, and because Xwayland will not allow an X11 client to move the pointer while the cursor is visible, the requests will fail.

Add a workaround for such X11 clients, when the cursor is being shown, keep it invisible until the cursor is actually moved. This way, X11 clients which show their cursor just before moving it would still have a chance to succeed.
