A new class Image_Diff for comparison of images and a draw-command "diffimage", which compares 2 images. Image_PixMap redesigned to provide interface for low-level image operations. New Image_AlienPixMap class now intended for Save/Load functionality. Aspect_PixMap class dropped. Xw_PixMap and WNT_PixMap classes now do not inherit from Aspect_PixMap and deprecated. ToPixMap methods now retrieve Image_PixMap as argument. Conflicts: src/ViewerTest/ViewerTest.cxx Remarks applied Fix compilation (correct merging error) Eliminated Aspect <-> Image cyclic dependency Fixed GIF dump in case of BGR32 image format
