<p>
The names of the icons to be used by the scale button. 
The first item in the array will be used in the button 
when the current value is the lowest value, the second 
item for the highest value. All the subsequent icons will 
be used for all the other values, spread evenly over the 
range of values.
</p>
<p>
If there's only one icon name in the <em class="parameter"><code>icons</code></em> array, it will 
be used for all the values. If only two icon names are in 
the <em class="parameter"><code>icons</code></em> array, the first one will be used for the bottom 
50% of the scale, and the second one for the top 50%.
</p>
<p>
It is recommended to use at least 3 icons so that the 
<a class="link" href="GtkScaleButton.html" title="GtkScaleButton"><span class="type">GtkScaleButton</span></a> reflects the current value of the scale 
better for the users.</p>
