<summary>
A GtkIconSource contains a <see cref="T:Gdk.Pixbuf" /> (or image
filename) that serves as the base image for one or more of the
icons in a <see cref="T:Gtk.IconSet" />, along with a
specification for which icons in the icon set will be based on
that pixbuf or image file. An icon set contains a set of icons
that represent the same logical concept in different states,
different global text directions, and different sizes.
</summary>
<remarks>
<para>
A GtkIconSource contains a <see cref="T:Gdk.Pixbuf" /> (or image
filename) that serves as the base image for one or more of the
icons in a <see cref="T:Gtk.IconSet" />, along with a
specification for which icons in the icon set will be based on
that pixbuf or image file. An icon set contains a set of icons
that represent the same logical concept in different states,
different global text directions, and different sizes.
</para>
<para>
So for example a web browser's "Back to Previous Page" icon
might point in a different direction in Hebrew and in English;
it might look different when insensitive; and it might change
size depending on toolbar mode (small/large icons). So a
single icon set would contain all those variants of the
icon. <see cref="T:Gtk.IconSet" /> contains a list of <see cref="T:Gtk.IconSource" /> from which
it can derive specific icon variants in the set.
</para>
<para>
In the simplest case, <see cref="T:Gtk.IconSet" /> contains
one source pixbuf from which it derives all variants. The
<see cref="C:Gtk.IconSet(Gdk.Pixbuf)" /> constructor handles
this case; if you only have one source pixbuf, just use that
function.
</para>
<para>
If you want to use a different base pixbuf for different icon
variants, you create multiple icon sources, mark which
variants they'll be used to create, and add them to the icon
set with <see cref="M:Gtk.IconSet.AddSource(Gtk.IconSource)" />.
</para>
<para>
By default, the icon source has all parameters
wildcarded. That is, the icon source will be used as the base
icon for any desired text direction, widget state, or icon
size.

If the widget state is wildcarded, this source can be used

<para>
<see cref="T:Gtk.IconSet" /> will normally transform
wildcarded source images to produce an appropriate icon
for a given state, for example lightening an image on
prelight, but will not modify source images that match
exactly.
