This might be true for controls that are based on native controls like 
TEdit or TButton, but not for LCL-only controls like TLabel. So there 
special handling is needed and to make it as easy as possible for the 
application developer this needs to be handled by the LCL. Felipe has 
already implemented the base for this and a Mac OS X implementation. 
Implementations for GTK, Qt and Windows are still missing though.
