TileRendererBase.GLEL.display(): Skip tile-rendering if TR is not yet setup. Sync issue w/ NEWT/AWT based GLAD
NEWT based GLDrawables may trigger GLAD display() via native repaint events.
If using in conjunction w/ AWT, i.e. NewtCanvasAWT and setupPrinting(..) has been called
and it's attched to the TR .. it could happen that display tries to issue beginTile()
before the TR is being setup.
This patch mitigates this issue (while not removing it) by querying whether setup is completed.
