public void set_label (string? label)
Sets the currently displayed value of this to the string in label.
Setting an empty label removes the emblem.
Note that this is meant for displaying short labels, such as roman numbers, or single letters. For roman numbers, consider using the Unicode characters U+2160 - U+217F. Strings longer than two characters will likely not be rendered very well.
If this method is called, and a number was already set on the icon, it will automatically be reset to zero before rendering the label, i.e. the last method called between set_label and set_count has always priority.
