 // By default, the contentView does not occupy the full size of a framed
 // window. Chrome still wants to draw in the title bar. Historically, Chrome
 // has done this by adding subviews directly to the root view. This causes
 // several problems. The most egregious is related to layer ordering when the
 // root view does not have a layer. By giving the contentView the same size as
 // the window, there is no longer any need to add subviews to the root view.
 //
 // If the window does not have a titlebar, then its contentView already has the
 // same size as the window. In this case, this class has no effect.
 //
 // This class currently does not support changing the window's style after the
 // window has been initialized.

You moved the @interface from the .mm to the .h, but failed to move the comment
over. This makes it very difficult to tell what this class is used for, and what
your subsequent method forceFrameSize: does.

Done.

+// This method allows us to set the content view size since setFrameSize is
+// overridden to prevent the view from shrinking
+- (void)forceFrameSize:(NSSize)size;
