Bugfix/fix continous streaming
Submit the next pixel to pixel2coord for getting the correct bottom-right coordinate
Merge branch 'master' of https://github.com/52North/IlwisCore.git
coordinate transformation should be done when the coordinate systems are different, not when they are equal
added an extra errorobject derivative for memory problems
some improvements for memory management of big rasters. vector.clear() doesnt free memory; it only frees memory when it goes out of scope. so a correct way of deallocation is in the unload method is to replace it with an empty vector which forces the original vector out of scope.
factory objects will now also be put in the internalcatalog; more consistent than the other way. code is set correctly from a name now
