+ * A class to help calculate the current width of a chat delegate/bar.
+ *
+ * The aim is to support a dynamic sizing based upon the width of the page. There is
+ * a built in curve that allows the width to transition between two percentages based
+ * upon a start and finish break point. This is to provide better convergence where
+ * generally the delegate will need to fill all or most the screen when thin but
+ * should max out in size and only fill a lower percentage of the screen when wide.
+ *
+ * @note While the main intended usage is to start with a high percentage when the parentWidth
+ *       is small and transition to a lower one when large, the math is setup for the
+ *       general case so any combination of parameters works.
