-// ThemeInstallBubbleView is a view that provides a "Loading..." bubble in the
-// center of a browser window for use when an extension or theme is loaded.
-// (The Browser class only calls it to install itself into the currently active
-// browser window.)  If an extension is being applied, the bubble goes away
-// immediately.  If a theme is being applied, it disappears when the theme has
-// been loaded.  The purpose of this bubble is to warn the user that the browser
-// may be unresponsive while the theme is being installed.
-//
-// Edge case: note that if one installs a theme in one window and then switches
-// rapidly to another window to install a theme there as well (in the short time
-// between install begin and theme caching seizing the UI thread), the loading
-// bubble will only appear over the first window, as there is only ever one
-// instance of the bubble.
