passing Context into Application?

[Mario Torre]

Why not having a marker interface, perhaps FXContext or ApplicationContext.
You then need to provide the implementation with appropriate methods to
access the environment and the app code would then need still casting, but
at least there is no Object going around, so it's a tiny little bit nicer
API wise.

Cheers,
Mario
