Version 2.7.
Added normalization of individual fractional delay filters. This reduced peak error by 3 dB, which is substantial for image resizing.
Reoptimized all filter parameters resulting in better frequency response linearity.
Added AVIR_NOCTOR macro to avoid copy-constructing and copying objects of some classes via a default copy function.
Added copy-constructor and assignment operator to the CImageResizerVars class, to avoid uninitialized memory copying.
Corrected automatic image offseting and "k" factor on image upsizing.
