  12     Buttons on a ribbon button bar can each come in three sizes: small, medium,
  13     and large. In some places this is called the size class, and the term size
  14     used for the pixel width and height associated with a particular size
  15     class.
  16
  17     A button can also be in zero or more hovered or active states, or in the
  18     disabled state.

  95     A ribbon button bar is similar to a traditional toolbar. It contains one or
  96     more buttons (button bar buttons, not wxButtons), each of which has a label
  97     and an icon. It differs from a wxRibbonToolBar in several ways:
  98       @li Individual buttons can grow and contract.
  99       @li Buttons have labels as well as bitmaps.
 100       @li Bitmaps are typically larger (at least 32x32 pixels) on a button bar
 101         compared to a tool bar (which typically has 16x15).
 102       @li There is no grouping of buttons on a button bar
 103       @li A button bar typically has a border around each individual button,
 104         whereas a tool bar typically has a border around each group of buttons.

 111         Triggered when the dropdown region of a button on the button bar is
