See RT-40184 for a description of the general problem. As with the shipping samples we need to remove the references to com.sun.** FX classes in order for them to continue working with the modular JDK.

Since the toys are all supposed to be self-contained, we don't want to create common utility classes in most cases; we will likely end up remove much of the code that was using the internal classes and methods (e.g., performance tracking).

Exceptions might be made in some cases, but we don't want wholesale copying of internal FX classes.
