Subject: stretchpoint issues
The spec says: "The draw:path-stretchpoint-x and draw:path-stretchpoint-y attributes specifies the stretchpoint of a shape." I happen to know that the stretchpoint is the same as the VML "limo-stretch point". This is what the VML spec says: "The limo-stretch definition and the formulas element (described below) allow greater designer control of how the path scales. They allow, for example, definition of a true rounded corner rectangle where the corners remain circular even though the rectangle is scaled anisotropically." See: http://www.w3.org/TR/1998/NOTE-VML-19980513 In neither spec is it described how the stretchpoint actually affects the calculation of the shape's vertices. While the formulas can reference the stretchpoint, it is easily demonstrated that the stretchpoint has an additional undocumented effect. Also, while the stretchpoint is defined relative to the svg:viewBox coordinate system, the spec does not mention that. In fact, svg:viewBox says only "this user coordinate system is used by the svg:points attribute and the <draw:path> element". Thanks, Chris
