This class can be used to generate an image with aligned text in it.
It creates an image with a given width and height and renders a text string in it.
The text may be align to the left, right, center or justified relatively to the image width.
The text font, size, background and foreground colors are configurable.
The generated image may be served as the current script output or stored in a server side file in the PNG, JPEG or GIF formats.
