Image_Color - removed semibroken summ/difference operators. Image_Diff now uses signed integer for computing differnce between ubyte3 components; properly compare squared tolerance. Image_Diff - dropped declaration of Image_ColorXXX24. RGB color difference is now computed using Chebyshev distance instead of Euclidean distance Image_PixMap - added methods RawValue()/ChangeRawValue() returning a pointer to image where specified pixel data is defined.
