+  /* Try and fix [Cursor] overriding [HintText] due to them being
+   * displayed in the same location on screen (both entered in the box).
+   * Idea:
+   *   - [Cursor] and [HintText] should coexist and be displayed at the
+   *     same time
+   *   - for visual integrity, entering a character and changing visual
+   *     focus to the next pin field should lead to only minimal changes
+   *     -> [HintText] should not have a different position with/without
+   *        [Cursor]
+   *     -> [HintText] should be displayed in the center of the box
+   *     -> [Cursor] should not be displayed in the center of the box if a
+   *        [HintText] is also present
+   *     -> [Cursor] should be displayed in front of [HintText] or behind
+   *   - [Cursor] typically is (on input fields with left-justified text) after
+   *     already typed characters
+   *   - [HintText] typically is displayed only when no characters have been
+   *     entered yet
+   *     -> [Cursor] should be displayed in front of the [HintText] at least
+   *        with TextDirection.LTR
+   *   - for minimal disruption in the existing codebase, this fix proposes to
+   *     add an optional positional or named Parameter [Offset] offset with a
+   *     default value of Offset.zero
+   *   - the offset would be added to the location given by rect prior to
+   *     drawing
+   *   - this function can then be called offsetting the [Cursor] to be drawn
+   *     to the left or right of [HintText]
