// 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.
