This task is mostly a question for now.
We have a few legacy APIs that require a callback to create a single object, based on some input data or string.
Examples: drag & drop (for the floating image object), textblock items (emoticons), ...
I honestly couldn't figure out how to create an image factory for those. Efl.Ui.Image.Factory requires a Model. I have no idea how to create a Model at the moment, and this may look overkill for something like textblock. Definitely overkill for copy & paste.
