apps/graphics/NxWidgets: Fix a possible deadlock condition when waiting for window geometry data that will never come. Fixed by re-requesting geometry data if we don't already have it.
apps/graphics/twm4nx: Add some debug output.
apps/graphics/twm4nx: Rethink how background events are handled.
apps/grephics/twm4nx: Expermimental organization to capture background events.
