+// 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).
