-  Michalis comments: note that GdkGLDrawable is an interface,
-  not a class, so
-  - it's GDK_GL_DRAWABLE_GET_CLASS is implemented using
-    GDK_GL_DRAWABLE_GET_INTERFACE instead of GDK_GL_DRAWABLE_GET_CLASS
-  - 1st field of class record is
-      base_iface: TGTypeInterface;
-    instead of
-      parent_class: TGObjectClass;
-  - Also (this is of course minor thing that does not affect
-    code using this unit, but still it is preserved in this translation
-    of C headers to Pascal) names of params of macros are vtable and inst.
