[The win-x and win-y refer to the window coordinate system; that is, they represent the scaled coordinates of the element. These values are supplied by the extension and will be overwritten (how rude!) if the author attempts to set them directly.]
A g-element has a number called the win-x. The win-x is usually 0.
A g-element has a number called the win-y. The win-y is usually 0.
