TiledPrintingAWTBase: Fix scaling - Fit frame to page, add MSAA RenderingHints test; setupPrint(Graphics2D): Query RenderingHints to use MSAA rendering

- AWTPrintLifecycle.setupPrint(Graphics2D): Query RenderingHints to use MSAA rendering
  - Impl. in GLCanvas
  - TODO GLJPanel (would need a new offscreen buffer)

- TiledPrintingAWTBase:
  - Fix scaling - Fit frame to page
  - add MSAA RenderingHints test

- GLCanvas: Remove dumpStack() DEBUG output
