These coordinates contain the all-time accumulated buffer attach point, which is a way to perform incremental client-side initiated movement of windows, intended as a way to maintain logical window positioning while compensating for layout changes such as folding in a left side panel. This value is not useful for implementing this feature, and break things if they ever become non-zero. Their inclusion in calculations also tend to cause confusion. Remove usage of these coordinates, removing the ability for clients to move themselves. This may again be supported if a better API is made available from wlroots.
