Warning
gtk_icon_source_set_size_wildcarded has been deprecated since version 3.10 and should not be used in newly-written code. Use GtkIconTheme instead.
If the icon size is wildcarded, this source can be used as the base
image for an icon of any size. If the size is not wildcarded, then
the size the source applies to should be set with
gtk_icon_source_set_size() and the icon source will only be used
with that specific size.
GtkIconSet prefers non-wildcarded sources (exact matches) over
wildcarded sources, and will use an exact match when possible.
GtkIconSet will normally scale wildcarded source images to produce
an appropriate icon at a given size, but will not change the size
of source images that match exactly.
