passing Context into Application?

I've been working on using the Android API's in a JavaFX application. As
explained in my blog post at we're
using a (imo) rather dirty trick.
The problem is that all Android API's need to be accessed via a Context
instance. The Java FXActivity that we use to bootstrap the JavaFX
Application extends Context, but it is only accessible in the JavaFX app
since we add it as a static field on FXActivity. When FXActivity calls the
LauncherImpl to start the application, we can't pass context information.
We can pass String[] but that is not useful here.

In general, I think the environment that launches a JavaFX Application
(Android, iOS, script, JNLP, management software,...) may want to pass some
context information. Of course this context information is very specific,
with Object being the ugly common denominator.

I realize it goes against the wora principles, but having the possibility
to either inject or set a context on javafx.application.Application would
definitely help using JavaFX in other environments.
