Why ippiResizeSqrPixel functions are deprecated?

Hello,

During migrating my codes from IPP7 into IPP8, I found that ippiResizeSqrPixel functions are deprecated.

I use them to resize medical data. Fine control of zoom factor and shift is crucial because we need them to overlay multiple medical images at exact position.

However, new ippiResize* functions don't take zoom factor / shift argument any more.

Only substitute for ippiResizeSqrPixel seem to be ippiWarpAffine function, but ippiWarpAffine is too slow compared with ippiResizeSqrPixel.

Is there any other way to resize image with  zoom factor / shift?

Thank you!
