This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
Starting from Tizen 8.0, the cbhm package is not distributed. Therefore, support the platform's clipboard feature using the ecore_wl2 APIs. ecore_wl2_offer_receive() and ecore_wl2_offer_mimes_get() can be found in Tizen 5.5 rootstrap, but are not distributed in the actual ecore_wl2 header. Therefore, this feature is supported starting from tizen 6.5. This feature supports TV profiles of Tizen 6.5 or higher. However, in Tizen 6.0 and below, copy&paste is supported only for data within the application.
