* for ellipsis while evas used -1.0 (no ellipsizing).
* this was moderately okay for a time because nobody was using it or GROUP parts
* with text in them very frequently, and so nobody noticed that the mismatch was breaking
* sizing in some cases when the edje ellipsis value failed to be applied,
* which occurred any time text.min_x was set; in this case, ellipsis would NEVER be
* correctly applied, and instead the text object would only ever get the first
* ellipsis_set(0), permanently breaking the part.
* the only way to fix this while preserving previous behavior was to bump
* the edje file minor version and then check it here to ignore "unset" ellipsis
* values from old file versions.
* the downside is that this will break old files which have text.min_x set to 0...maybe.
