add Builder.drawTo(Grapgics2D g, ...) method

[GoogleCodeExporter]

Please add Builder.drawTo(Grapgics2D g, ...) to write the thumbnail to existing 
graphics directly.

Once again, thank you for your suggestion.

I'm trying to think of an exact use case for this function.
Perhaps, passing a pre-tranformed `Graphics2D` object to which the thumbnail 
should be drawn on?

Internally, the smallest unit used for processing is a `BufferedImage` object, 
and any drawing is done by first obtaining an `Graphics2D` object from the 
`BufferedImage` rather than passing around `Graphics` objects. (Reworking the 
internals to pass around `Graphics` objects would be a very large endeavor 
which I feel doesn't have a good return on investment.)

Therefore, a hypothetical `Builder.drawTo(Graphics g)` method would just be a 
method which internally draws the `BufferedImage` onto the given `Graphics` 
object.

If that's all that's needed, it shouldn't be too difficult to add to the 
`Builder` class, but I feel that's something that could be done just as simply 
outside of the Thumbnailator API:

  Graphics g = getGraphicsFromSomewhere();

  BufferedImage img = 
    Thumbnails.of("path/to/image")
      .size(100, 100)
      .asBufferedImage();

  g.drawImage(img, 0, 0, null);

This issue has been open for more than 6 months without much interest (only a 
single star has been given), and I find it difficult to find an use case for 
this addition, so I'll be closing this issue without additional action.
