	* gnu/java/awt/peer/gtk/GtkTextAreaPeer.java,
	jni/gtk-peer/gnu_java_awt_peer_gtk_GtkTextAreaPeer.c
	(native	create): Add width and height parameters.  Set text
	view's size request according to new parameters.
	(create): Calculate text view size based on current font's
	metrics and number of rows and columns.  Set TextArea's font if
	not already set.  Call native create.
	(getMinimumSize): Call minimumSize.
	(getPreferredSize): Call preferredSize.
	(getHScrollbarHeight): New method.
	(getVScrollbarWidth): New method.
	(minimumSize): Calculate minimum size based on scrollbar
	visibility, scrollbar sizes, font metrics and number of rows and
	columns.
	(preferredSize): Likewise for preferred size.
	(gtkTextGetSize): Remove method.
