 * @GTK_ALIGN_END: snap to right or bottom side, leaving space on left
 *     or top
 * @GTK_ALIGN_CENTER: center natural width of widget inside the
 *     allocation
 * @GTK_ALIGN_BASELINE: align the widget according to the baseline. Since 3.10.
 *
 * Controls how a widget deals with extra space in a single (x or y)
 * dimension.
 *
 * Alignment only matters if the widget receives a “too large” allocation,
 * for example if you packed the widget with the #GtkWidget:expand
 * flag inside a #GtkBox, then the widget might get extra space.  If
 * you have for example a 16x16 icon inside a 32x32 space, the icon
 * could be scaled and stretched, it could be centered, or it could be
 * positioned to one side of the space.
 *
 * Note that in horizontal context @GTK_ALIGN_START and @GTK_ALIGN_END
 * are interpreted relative to text direction.
 *
 * GTK_ALIGN_BASELINE support for it is optional for containers and widgets, and
 * it is only supported for vertical alignment.  When its not supported by
 * a child or a container it is treated as @GTK_ALIGN_FILL.
