Subject: [E-devel] Ecore: Save proper evas engine buffer depth when
_ecore_evas_resize is done

I have found bug in ecore evas buffer. It is created by default as RGB32,
and then it can be changed by ecore_evas_alpha_set function, but when resize
is done it is always created as ARGB32.

Patch in attachment checks in resize if alpha channel is set, and then set
appropriate buffer depth.
