------------------------------+---------------------------------------------
 Writing a map which has nested layers via OWSContext discards the
 layer.metadata.nestingPath. This is caused by the function decomposingPath
 which pops elements from the metadata array passed by reference.

 The supplied patch creates a copy of the passed in array.
