I also want to make sure that we don't initialize the AWT toolkit unless an application tries to load an image file of a format that JavaFX doesn't support. It will take some time to review and test it.

Independent of whether loading `ImageIO` will initialize AWT, I've modified the code such that `ImageIO` will only ever be loaded if we encounter an image format that JavaFX can't load.
