ecore-evas/buffer: implement ignore_events method 

Summary:
this is a simple implementation of ignore_events functionality which
sets pass_events if it's an image or prevents the emission of events
in other cases

the result should be that no user events are received. this deliberately
does not block the triggering of resize callbacks as in the original ticket
since this guarantees broken functionality and is just not a good idea
