We expose the image resolution related GD functionality to userland by introducing `imageresolution()` as getter/setter. Given only the image argument, it returns the current resolution as indexed array. Given only a second argument, it sets the horizontal and vertical resolution to this value. Given three arguments, it sets the horizontal and vertical resolution to the given arguments, respectively.
