+/**
+ * @brief Append a regularly defined set of sized icon images to a QIcon.
+ *
+ * The following usage example assumes the resources ":myIcons/16x16/exit.png",
+ * ":myIcons/24x24/exit.png", and ":myIcons/32x32/exit.png" are available and
+ * that we want to bundle them together into exitIcon.
+ *
+ * \code
+ *   QList<int> sizes; sizes << 16 << 24 << 32;
+ *   QIcon exitIcon;
+ *   buildIcon(&exitIcon, ":myIcons/%size%/exit.png", sizes);
+ * \endcode
+ *
+ * Does NOT check whether the referenced resources actually exist.
+ *
+ * @param theIcon Pointer to the icon that will be built/appened to.
+ * @param iconRscTemplate A tag-based template string for the icon resource.
+ *                        Two tags are recognized in iconRscTemplate: \%size\%
+ *                        and \%dim\%. When the iconRscTemplate is expanded, the
+ *                        tag \%dim\% will be replaced by {iconSize} and
+ *                        \%size\% will be replaced by {iconSize}x{iconSize},
+ *                        where {iconSize} is a string cast of an element in
+ *                        sizeList.
+ * @param sizeList A list of single-dimension sizes to be added to the icon.
+ *
+ * @return void
