Obtains the pixel size of a semantic icon size size: GTK_ICON_SIZE_MENU, GTK_ICON_SIZE_BUTTON, etc. This function isn’t normally needed, IconTheme.loadIcon is the usual way to get an icon for rendering, then just look at the size of the rendered pixbuf. The rendered pixbuf may not even correspond to the width/height returned by IconSize.lookup, because themes are free to render the pixbuf however they like, including changing the usual size.
