Subject: Makefile.am: Add GdkPixbufDecoder.java and
 gnu_java_awt_peer_gtk_GdkPixbufDecoder.c

2003-11-11  Thomas Fitzsimmons  <fitzsim@redhat.com>

	* Makefile.am: Add GdkPixbufDecoder.java and
	gnu_java_awt_peer_gtk_GdkPixbufDecoder.c
	* Makefile.in: Regenerate.
	* gnu/java/awt/image/ImageDecoder.java (ImageDecoder(byte[],int,int)):
	New constructor.
	(startProduction): Create ByteArrayInputStream when url and filename are
	null.
	(produce): Declare stream parameter as InputStream.
	* gnu/java/awt/image/XBMDecoder.java (produce): Declare stream parameter
	as InputStream.
	* gnu/java/awt/peer/gtk/GdkPixbufDecoder.java
	(GdkPixbufDecoder(byte[],int,int)): New constructor.
	(produce): Declare stream parameter as InputStream.
	* gnu/java/awt/peer/gtk/GtkComponentPeer.java (prepareImage): Throw NPE
	if image is null.  Set image's observer before running PrepareImage
	thread.  Pass image to startProduction.
	* gnu/java/awt/peer/gtk/GtkImage.java: Add null checks before calls to
	source's member functions.
	(observer): New field.
	(setObserver): New method.
	(setDimensions, setPixels, imageComplete): Call observer's imageUpdate.
	* gnu/java/awt/peer/gtk/GtkToolkit.java (checkImage, getImage): Return
	new GtkImage.
	(prepareImage): Implement.
	* java/awt/Component.java: Add static fields incrementalDraw and
	redrawRate.
	(imageUpdate): Implement.
	(createImage): Call Toolkit's createImage if peer is null.
	(prepareImage): Throw NPE if image is null.
	* java/awt/MediaTracker.java: Fix return value.
