Load vertex positions for layouts in rectangle class. This will be used for proper rotation adjusting. Add latest muunt editor files. Add somewhat functional mk8 camera bin editor. Points can be moved around. The map orientation determines the position of the icons to map over the model. Fix window content UV map for layouts. Add 2D KCL renderer for top down KCL preview for both muunt and camera editors.
