Before this patch, we used legacy X11 xcursor names, and didn't really have any fallback handling in place (we only tried to fallback to "xterm", regardless of which cursor shape we were trying to load). This patch changes two things: 1. Improved fallback support. cursor_shape_to_string() now returns a list of strings. This allows us to have per-shape fallbacks, and any number of fallbacks. 2. We prefer CSS xcursor names over legacy X11 names.
