Each window now has a tree of layout cells associated with it. In this tree, each node is either a horizontal or vertical cell containing a list of other cells running from left-to-right or top-to-bottom, or a leaf cell which is associated with a pane. The major functional changes are: - panes may now be split arbitrarily both horizontally (splitw -h, C-b %) and vertically (splitw -v, C-b "); - panes may be resized both horizontally and vertically (resizep -L/-R/-U/-D, bound to C-b left/right/up/down and C-b M-left/right/up/down); - layouts are now applied and then may be modified by resizing or splitting panes, rather than being fixed and reapplied when the window is resized or panes are added; - manual-vertical layout is no longer necessary, and active-only layout is gone (but may return in future); - the main-pane layouts now reduce the size of the main pane to fit all panes if possible. Thanks to all who tested.
