-// This 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.
-// Unfortunately, both of these themes render controls differently on the
-// different versions of Windows.
-//
-// In order to ensure maximum consistency of baselines across the different
-// Windows versions, we provide a simple implementation for DRT here
-// instead. These controls are actually platform-independent (they're rendered
-// using Skia) and could be used on Linux and the Mac as well, should we
-// choose to do so at some point.
