// 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.
