<p>Try to load a pixbuf from a source string. The source could be
an abolute path, an icon name or a filename that points to a

the Icon key of desktop files.</p>
<p>The pixbuf is never bigger than <em class="parameter"><code>dest_width</code></em>
and <em class="parameter"><code>dest_height</code></em>

If it is when loaded from the disk, the pixbuf is scaled
preserving the aspect ratio.</p>
