Status: Rejected
Change Description: no spec change
Rationale: No. The points are points, not pixels. They're giving the precise coordinates of the rectangle to copy; they're not giving pixel coordinates of the data in that rectangle. In fact there might be more or less than one pixel per unit coordinate.
