Also there's the opposite possibility of lines being spaced ridiculously far apart. Either possibility would break edje's claim to making it easy to adapt nicely to different screen resolutions. The purpose here was to provide some way to space lines of text. So a padding, margin, or line spacing would be good as well and avoid the issue you are talking about. It comes with it's own issues, but the theme has a lot of control and could potentially base it's padding/margins off the font size if there are proper signals in place. If one of these properties already exists, I was unable to find it. I'm not sure I understand Thomas' issue right, but if I do then it sounds like a bug to me.

An exception might be if the valign of the text widget is specifically meant to apply to the first line only, in which case I would question it's usefulness. The issue is the valign property for textblock applies to the lines. This is useless as there is no padding or margins to make the property of any use. The line will always be in the same position as the line height is the same as the font height. The align on the textblock part should work though. The issue might be that the textblock doesn't report it's height correctly or something. If you think about the align textblock property you'll note it works on a line by line basis and not the whole block. It would be interesting to know if the align on the part itself works horizontally as well. If not then it could be another pointer to the textblock not reporting it's size. Since I haven't touched much edje internals, it's just a guess. I had spent some time trying to figure out a way to achieve a certain effect, but ended up having to use some embryo to change the offset of the textblock to make it vertical align bottom and scroll up.
