[on Olli Pettay - due 2011-03-01]. CSS supports several unit types for angles[1]. They are used for transformations. InkML[2] uses deg and rad. But InkML uses angles for pen tilt and orientation. So not quite what we're doing. SVG might be closest to our case, since it has ellipses[3], and other shapes. I guess the initial decision for radiusX/Y in the events was based on the SVG syntax. In SVG that is enough, since one can use rx/ry and then the generic rotate(deg) using the transform. But we need to have that all that data in the events (if we want to support all this). So, should we perhaps have this all working close to SVG? Having the current radiusX/Y and also rotationAngle (in deg (-90, 90])? -Olli [1] http://www.w3.org/TR/css3-values/#angles [2] http://www.w3.org/TR/InkML/ [3] http://www.w3.org/TR/SVG/shapes.html#EllipseElement
