NineTileBox class

This allows you to create a rectangle textured with a 9-sliced image.

How it works is that you have a template image in a 3x3 grid, made up of 9 tiles, and a new rectangle can be draw by keeping the 4 corners, expanding the 4 sides only in the direction in which they are located and expanding the center in both directions. That allows you to have non distorted borders.
