// This file (and its associated .h file) is a clone of RenderThemeMac.mm.
// Because the original file is designed to run in-process inside a Cocoa view,
// we must maintain a fork. Please maintain this file by performing parallel
// changes to it.
//
// The only changes from RenderThemeMac should be:
// - The classname change from RenderThemeMac to RenderThemeChromiumMac.
// - The introduction of RTCMFlippedView and FlippedView() and its use as the
// parent view for cell rendering.
// - In platformFocusRingColor(), the use of ChromiumBridge to determine if
// we're in layout test mode.
// - updateActiveState() and its use to update the cells' visual appearance.
// - All the paintMedia*() functions and extraMediaControlsStyleSheet()
// are forked from RenderThemeChromiumSkia instead of RenderThemeMac.
//
// For all other differences, if it was introduced in this file, then the
// maintainer forgot to include it in the list; otherwise it is an update that
// should have been applied to this file but was not.
// The methods in this file are specific to the Mac OS X platform.
// FIXME: The platform-independent code in this class should be factored out and merged with RenderThemeSafari.
