From: 이상진 <lsj119@samsung.com>

I am attaching another patches for transparent window.

1. Use RGB Visual.
2. Set destination_alpha in ecore_evas for alpha composite in evas.
3. add Function
   - Ecore_Evas_Engine_Func->fn_transparent_set
   - ecore_evas_transparent_set , ecore_evas_transparent_get
   - elm_win_transparent_set, elm_win_transparent_get
