/**
 * A #GtkSpinButton is an ideal way to allow the user to set the value of
 * some attribute. Rather than having to directly type a number into a
 * #GtkEntry, GtkSpinButton allows the user to click on one of two arrows
 * to increment or decrement the displayed value. A value can still be
 * typed in, with the bonus that it can be checked to ensure it is in a
 * given range.
 * 
 * The main properties of a GtkSpinButton are through an adjustment.
 * See the #GtkAdjustment section for more details about an adjustment's
 * properties. Note that GtkSpinButton will by default make its entry
 * large enough to accomodate the lower and upper bounds of the adjustment,
 * which can lead to surprising results. Best practice is to set both
 * the #GtkEntry:width-chars and #GtkEntry:max-width-chars poperties
 * to the desired number of characters to display in the entry.

 * GtkSpinButtons main CSS node has the name spinbutton. It creates subnodes
 * for the entry and the two buttons, with these names. The button nodes have
 * the style classes .up and .down. The GtkEntry subnodes (if present) are put
 * below the entry node. The orientation of the spin button is reflected in
 * the .vertical or .horizontal style class on the main node.
