Example 4 with CompositeType

             * Fix for bugid 4783274 - BlitBg throws an exception for
             * a particular set of anomalous parameters.
             * REMIND: The native loops do proper clipping and would
             * detect this situation themselves, but the Java loops
             * all seem to trust their parameters a little too well
             * to the point where they will try to process a negative
             * area of pixels and throw exceptions.  The real fix is
             * to modify the Java loops to do proper clipping so that
             * they can deal with negative dimensions as well as
             * improperly large dimensions, but that fix is too risky
             * to integrate for Mantis at this point.  In the meantime
             * eliminating the negative or zero dimensions here is
             * "correct" and saves them from some nasty exceptional
             * conditions, one of which is the test case of 4783274.
