 // TestShellWebTheme::Engine implements the WebThemeEngine
 // API used by the Windows version of Chromium to render native form
 // controls like checkboxes, radio buttons, and scroll bars. The normal
 // implementation (native_theme) renders the controls using either the
 // UXTheme theming engine present in XP, Vista, and Win 7, or the "classic"
 // theme used if that theme is selected in the Desktop settings.
