// A class that implements a bubble that consists of the following items:
// * one icon ("icon")
// * one title text ("title")
// * one close button ("x")
// * one message text ("message")
// * one optional link ("link")
// * two optional buttons ("ok" and "cancel")

// This bubble is convenient when we wish to ask transient, non-blocking
// questions. Unlike a dialog, a bubble menu disappears when we click outside of
// its window to avoid blocking user operations. A bubble is laid out as
// follows:
//
//   +------------------------+
//   | icon title           x |
//   | message                |
//   | link                   |
//   |          [Cancel] [OK] |
//   +------------------------+
