[E-devel] [PATCH] elm_icon is disappeared when theme hook is called.

Dear All,

[Current Issue]
 - The elm_icon can be disappeared when theme hook is called.
   You can see the problem in the below situation.
    a) elementary_test -> Layout select
    b) elementary_config -> Fonts(toolbar) -> select some font class, font,
style, size
    c) Select "Apply" button
   then two icons in title layout are disappeared.

[Main cause]
 - when theme hook is called, internally _elm_image_smart_sizing_eval
function is called.
   The function calculates icon's min, max size. 
   But min, max size is calculated  only in case no_scale is true or
resize_down or resize_up is false.
   If application isn't set no_scale or resize_down/up, minw and minh value
is just -1.
   So when theme hooks is called then sizing_eval is called, icon's min size
is -1 and that is disappeared.

[Change Description]
 - I just added evas_object_size_hint_min_get(obj, &minw, minh) in
_elm_image_smart_sizing_eval.
    Patch is working well, but I don't think this is right solution because
that would break image(icon) min,max concept

Please review the attached patch.

Thanks.
