Lightweight Java Game Library Code

Added floating point format to PixelFormat. Linux implementation

Removed Keyboard.isStateKeySet() - it is easily replaced by Toolkit.getLockingKeyState()

Mac OS X: Catch exceptions from getLockingKeyState

Mac OS X: Implement Display.isStateKeySet()

AWT: Support re-entrant redrawing (by the same AWT thread). This happens when displaying dialog boxes from paintGL() or initGL()
