Experiment: Rich Text Sprite Object

[pathunstrom]

Start making text nicer to work with.

The first pass is getting the resolution of the rendered text to more closely match the AABB of the sprite object. We can write this in such a way that when the text of the sprite changes, we update the target aspect ratio, and then changes to width and height work like the camera: attempt best fit.

After that: lots of things IE supporting resizing, italics, bold, scrolling text boxes, outlines of the text box itself
