Adjust text content to fit a defined width or height

Hey I've been working on this feature where you can scale down a textfield to either:

1. Fit a single line textfield to a defined width
2. Fit a multi line textfield to a defined height

here is my first pass, do you feel like it belongs in this project? If so, there is much to do before it can be pulled in. Not sure the proper place for the utilities and I'm sure it can be optimized better. Let me know you thoughts =]

here is the initial commit: https://github.com/gltovar/flixel-ui/commit/8eefdad0fbdb3af1d1c99ce66dd2cf6aa2bf6a60

here is a screen shot: http://i.imgur.com/TSzBtYY.png

and the code that generated that screenshot: https://gist.github.com/gltovar/6881361

Start by reviewing the linked initial commit and the screenshot-generation gist to understand the proposed behavior. The issue names no repository files, tests, or acceptance criteria; work is not ready to begin until the project decides whether the feature belongs and defines its scope, utility location, and expected results.
