[Insight-developers] Compile errors in GPUCommon

[Kris Zygmunt]

Interesting!  It looks like itkGPUImageDataManager.h is both including  
itkGPUImage.h and providing a forward declaration of GPUImage, while  
GPUImage needs to include itkGPUImageDataManager.h.  Thus, removing  
the #include "itkGPUImage.h" from itkGPUImageDataManager.h in addition  
to your change should get it to compile (or at least it worked for me).
