+// 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.
