GdkGraphics2D.java: Implemented rendering hints related methods.

	* gnu/java/awt/peer/gtk/GdkGraphics2D.java:
	Implemented rendering hints related methods.
	(getDefaultHints): New helper method. Returns
	default rendering hints.
	(walkPath): changed to normalize path if
	the KEY_STROKE_CONTROL key is in "normalize" mode.
	(draw3DRect): changed coordinates of rectangle by +0.5
	if in "normalize" mode.
