+
+    A wrap sizer lays out its items in a single line, like a box sizer -- as long
+    as there is space available in that direction.
+    Once all available space in the primary direction has been used, a new line
+    is added and items are added there.
+
+    So a wrap sizer has a primary orientation for adding items, and adds lines
+    as needed in the secondary direction.
