	* libjava/java/awt/image/SinglePixelPackedSampleModel.java: New
	file.
	* libjava/java/awt/image/IndexColorModel.java: New file.
	* libjava/java/awt/image/ImageConsumer.java: Removed import of
	java.awt.ColorModel stub.

	* gnu/gcj/util/BitMaskExtent.java: New file, utility class.
	* gnu/gcj/util/Buffers.java: New file, utility class.
