FYI: ColorModel constructor tests


This patch (committed) adds some checks for the constructors in the ColorModel class:

2006-06-09 David Gilbert <david.gilbert@object-refinery.com>

   * gnu/testlet/java/awt/image/ColorModel/MyColorModel.java: New file,
   * gnu/testlet/java/awt/image/ColorModel/constructors.java: New file.

I didn't fix the failures in Classpath yet, because I'm still unfamiliar with the dependencies in this part of the code.

Regards,

Dave
