Please see the lcl/themes.pas unit

===================================
unit Themes;
{$mode objfpc}{$H+}
interface
uses
   // no Graphics or Controls can be used here to prevent circular
references
   //
   SysUtils, Types, GraphType, Math, Classes, LCLProc, LCLType, Graphics,
   TmSchema;
type
===================================

Note the code comment about "Graphics", but then that unit IS used in the uses clause. :)

I fixed the comment in r57276.
Controls indeed cannot be used there. It creates a circular reference.
