RangeLookUp computeRect is not threadsafe #206

RangeLookUp is a PointOpImage, as such the resulting image is computed in multithreading hence the computeTile method must be either threadsafe of syncronized.

Right now none of the two applies, hence under heavey parallelism RangeLookUp may throw ArrayIndexOutOfBound exception since its internal doLookup method uses member variable to store the location at which the computations is being performed.

From simboss1@gmail.com on January 07, 2013 16:39:07 I provided a tentative patch that duplicates some of the codes as JAI Core usually does when computing data in multithreaded ops.
