Comment 1 for bug 171488

I note that Inkscape has the zero coordinates at the bottom left, but SVG seem to use the top left, which is confusing when using the XML editor; granted using it is not the normal way of editing.
Being able to set the point of origin, as noted, would be handy.
Somewhat separately, some objects like circles are measured from the centre, others like rectangles from the top left, but Inkscape always uses the bottom left. Being able to set the object origin on the Tool Control bar like Illustrator would be a simple but great feature addition.
