-// 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 ThemeMac should be:
-// - The classname change from ThemeMac to ThemeChromiumMac.
-// - The import of FlippedView() and its use as the parent view for cell
-// rendering.
-// - In updateStates() the code to update the cells' inactive state.
-// - In paintButton() the code to save/restore the window's default button cell.
-// - The Snow Leopard focus ring bug fix and its use around every call to
-// -[NSButtonCell drawWithFrame:inView:].
-//
-// 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.
-
-// FIXME: Default buttons really should be more like push buttons and not like buttons.
-
-// --- START fix for Snow Leopard focus ring bug ---
-
-// There is a bug in the Cocoa focus ring drawing code. The code calls +[NSView
-// focusView] (to get the currently focused view) and then calls an NSRect-
-// returning method on that view to obtain a clipping rect. However, if there is
-// no focused view (as there won't be if the destination is a context), the rect
-// returned from the method invocation on nil is garbage.
-//
-// The garbage fortunately does not clip the focus ring on Leopard, but
-// unfortunately does so on Snow Leopard. Therefore, if a runtime test shows
-// that focus ring drawing fails, we swizzle NSView to ensure it returns a valid
-// view with a valid clipping rectangle.
-//
-// FIXME: After the referenced bug is fixed on all supported platforms, remove
-// this code.
-//
