windowType chooses how a Window builds and how an elevation marks it. A saved window with no windowType is a CASEMENT. The plan symbol is the same for every type.
The pictures show the elevation of a 1.20 × 1.20 m window. Mark lines meet at the hinge side. A sash opens to the right face of its wall, facing along the wall from its first point, so its marks are dashed when you look at the left face. windowSashCount(windowType) gives the number of sashes.
