Agreed, a native function is probably the only way to do it. But, all
Xlib drawing functions require a Display (usually trivial) and a Window or
Drawable. That Window or Drawable has to be the peer for the
corresponding Java object.
So, a native function that does ANY drawing on the screen must have access
to the correct peer Window or Drawable. But, how how do I get the peer
Window or Drawable from Java???

Not sure what you are referring to by 'graphics contexts'. I don't think
I need to pass a Java Graphics object to a native function, and 'graphics
context' has a specific meaning in Xlib which is something different than
Java's Grphics object.
