FYI: Expanded ColorConvertOp tests


Hi,

The following patch, committed, expands some of the ColorConvertOp
tests.

Regards,
Francis


2006-08-18  Francis Kung  <fkung@redhat.com>
	*
gnu/testlet/java/awt/image/ColorConvertOp/createCompatibleDestImage.java:
	(colorModelTest): Expand tests.
	(profileTest): Expand tests.
	(test): Clean up looping.
	*
gnu/testlet/java/awt/image/ColorConvertOp/createCompatibleDestRaster.java:
	(colorModelTest): Expand tests.
	(profileTest): Expand tests.
	(test): Clean up looping.
	* gnu/testlet/java/awt/image/ColorConvertOp/filterImage.java:
	(test3): Remove test of feature that is not implemented yet.
