 [patch] elm_cnp_helper - add type checking for non-elm cnp datas Date: Fri,
 16 Dec 2011 17:09:37 +0900

Dear developers

elm_cnp_helper supports rich types for copying & pasting.
but it doesn't extend like x11 way.
this patch introduces to reduce mismatch for checking selection type format.
now elm can live in harmony with non-elm cnp datas

Thanks
