Version 3.0.
Improved speed by 10-25% on upsizing by utilizing a special resizing function together with filter-less 2X upsizing. Does not apply to the de-interleaved (AVX) resizing.
Minor LANCIR optimization.

Version 2.9.
Removed a rarely-used half-band resizing step completely since it offers no practical performance nor quality benefits.
Optimized filter generation function (removed divisions by a constant) as filters are always post-normalized anyway. This may reduce overhead when creating thumbnail-sized images.

Version 2.8.
Fixed regression with the copy-constructor of CImageResizeVars class (previously it caused uninitialized accesses).
Removed filter length optimization as it did not reduce overhead measurably.
Optimized "peaked cosine" window function generator (removed division).
Added "unbiasing" to resizer - an unconventional approach which reduces peak error significantly, at the expense of 5% increased overhead.
Reoptimized filter parameters, now yielding an unprecedented quality.

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.
