Another option would be a "cursor-daemon" whose sole task it would be
to call XSetCursor regularly on all windows where an animated cursor
must be emulated. But that would require defining an selection- or
property-based protocol for Xcursor to communicate with that daemon...
probably overkill.

Good enough, I guess. And given XcursorSupportsAnimation(), themes could
even provide a separate image as fallback.
