LANCIR 3.0.5. The "virtual oversampling" has been removed from this version, for an even lower overhead. While it was a correct thing overall, it does not make much of a difference for Lanczos filter. Filter oversampling will likely be used in a future AVIR refactoring to create precise filters while not inducing a computational overhead - it looks like there is no practical need to perform full-featured input image upsizing/oversampling as half of image's samples are initially zero anyway. But for precise filter design oversampling is a necessity, like described on the project page; it has to be tested and analyzed if downsampling a designed oversampled filter works well (it should). So, LANCIR is now likely has a "production" quality level, its further development is not planned at the moment.
