Add method to save a JavaFX image to file without the use of SwingFXUtils?

[Kevin Rushforth]

Hi,

We've discussed adding image reading and writing functionality in the 
past. Something on the order of Java2D's Image I/O. Doing it right would 
be a large project, and would be more than just adding a couple methods 
to JavaFX Image. Unless and until we do that, using the SwingFXUtils to 
produce a BufferedImage from a JavaFX Image is the recommended approach.
