[E-devel] [Patch][elm_map] Add elm_map_overlays_get & elm_map_overlay_visible_get

[Bluezery <oh...@gm...>]

Dear EFL developers,

I want to add 2 new APIs (elm_map_overlays_get & elm_map_overlay_visible_get).

There are no way to get the group overlays because group overlay,
something like virtual overlay, is created and deleted dynamically.
So elm_map_overlays_get returns total overlay's list and user can get
any type of overlays including group overlays.
Overlays which is grouped can not be visible. Because overlay grouping
is performed by elm_map, user do not know whether overlays are visible
or not. So elm_map_overlay_visible_get is added for this reason.

Thanks
