// Draws and maintains Translate Infobar GUI.
// The translate bar changes unidirectionally between 3 states:
// 1. "Before Translate" - source language popup and translate/cancel buttons
//    visible.
// 2. "Translating" - "Translating..." status text visible in address bar.
// 3. "After Translation" - source & target language popups visible.
//
// The GUI uses popup menus interspersed in a text label.  For localization
// purposes this means we potentially need 3 labels to display the UI (the 3rd
// is only visible in certain locales).
