Extend the image loading capabilities of JavaFX by plugging into the javax.imageio API, allowing applications to use third-party libraries like TwelveMonkeys to load a wide variety of image formats.

The built-in JavaFX image loaders continue to be used for all supported image formats. If an image can't be loaded using one of the built-in image loaders, JavaFX will probe the ImageIO registry for image readers that can load the image instead.

This enhancement also requires support for variable-density images like SVG. Variable-density images will be rasterized using the screen's pixel density, ensuring they are rendered at a higher resolution on high-DPI screens.

The proposed feature works transparently across all JavaFX image APIs, including images referenced by stylesheets, and images contained in data-URIs.
