EWS is a new Ecor_Evas engine that builds on top of other engines. It
will create a backing store Ecore_Evas and ecore_evas_ews_new()
windows are created in it as images, but transparent to the outside
users (similar to buffer's ecore_evas_object_image_new()).
It provides a basic windowing system, with a known background object
that can be changed to your pleasure, and issue Ecore_Events to notify
of new windows and changes like movement, etc. Then you can write a
simple window manager based on it. (See example, Elementary will
contain one as well).
Backing store is determined by your best engine (as in
ecore_evas_new()) or specified with ecore_evas_ews_engine_set() or
environment variable $ECORE_EVAS_EWS (format:
engine-name❌y:w:h:options). The size can be set with
ecore_evas_ews_setup().
