-Edits will not save back to the file in memory on render completion when preview renderer is running. --Bug fixes -dc_perlin was crashing on Nvidia when using SP. -Duplicate images were randomly getting added to the file in memory. -Crash when opening an Xml with less than 2 flames in it. --Code changes -Use raw array of floats in OpenCL for perlin noise, rather than float3/double3. -Add some default cases to dc_perlin. -Redo singleton pattern yet again. Deriving from a templated Singleton<T> class was creating a separate instance per module. Now only one instance of each type will ever be created and it will be wrapped in a shared_ptr which guarantees its deletion as main() exits.
