object -- a gtk:image widget
size -- an integer with the new pixel size

Accessor of the pixel-size slot of the gtk:image class. The gtk:image-pixel-size function gets the pixel size used for named icons. The (setf gtk:image-pixel-size) function sets the pixel size. If the pixel size is set to a value not equal to -1, it is used instead of the icon-size property.
