FYI: java.awt.image.ConvolveOp new tests


I committed this patch:

2005-07-25  David Gilbert  <david.gilbert@object-refinery.com>

    * gnu/testlet/java/awt/image/ConvolveOp/constants.java: new file,
    * gnu/testlet/java/awt/image/ConvolveOp/constructors.java: new file,
    * gnu/testlet/java/awt/image/ConvolveOp/getKernel.java: new file.

Regards,

Dave Gilbert
