CSS syntax for animated properties

Animations need Java code to be defined and enabled for properties in JavaFX. While is is working and produces great results, in fact the role separation is void: Designers cannot speak Java, and they don't want to recompile an application just to get animated views.

Hence our proposal is to add a proprietary syntax to CSS. The syntax allows to specify either...
...a static value, just as it is right now
   (like -fx-opacity: 0.6)
...the name of an animation class, which is to be used to animate the property
   (like -fx-opacity: foo.bar.MyFader)
...a constructor syntax for animation classes, allowing to provide customization parameters
   (like -fx-opacity: foo.bar.MyFader(0.1, 0.3))

This syntactical extension allows a designer most flexibility, and even enables the existing JavaFX 8 animations like FadeTransition to be used out of the box by any CSS aware artist.
