you can't save an image if its being used as a proxy. all the data is in gpu
specific format (if you have something like gl) and thus is not accessible. if
you must have pixel data that's what the buffer canvas exists for. ecore_evas
can create them and return an image object that is filled with the buffer
canvas. elementary also wraps this with the inlined window. take a look at
those.
