Alignment options

[BasilChessman]

There are currently three alignment options in the text formatting section (left, center, & right). However, all three of those options are top justified. It would be advantageous to have the ability to choose center and bottom justifications as well. A relevant use case would be for something like a quote of the day block. In a block like that, the text is always top justified at the top of the bounding rectangle. Being able to center justify top to bottom and left to right would make for a much better look, especially when the quotes are of differing lengths. Additionally, having the font size grow and shrink according the size of the bounding box would be a plus. That way short quotes could expand to fill the designated space.
