Add snap to window edge framework Adds functions for calculation of distances between window edges, as well as for window growing and shrinking. All calculations are based on the "pending" geometry. Ignored from snapping: - views that do not share the same output - minimized views - maximized views - views that are neither: - part of the current workspace - part of the always-on-top tree

snap: cache and ignore last-snapped edge when growing or shrinking When growing or shrinking a view by snapping to an edge, a client may ignore the requested size and instead keep its original size or substitute a different (possibly constrained) size. In this case, the view may not actually contact the snapped edge, and a subsequent snap attempt will just keep re-trying (and failing) to contact the same ege. To mitigate this, remember the last-snapped view, snapping direction and offset of the snapping edge in snap.c; when re-attempting a snap for the same view in the same direction, ignore the edge that was last "hit", to allow snapping to progress beyond the problematic edge.
