[Mesa-dev] [PATCH 0/2] Implement lanczos scaling

[Nayan Deshmukh]

Hi guys,

I have tried to implement a simple lanczos filter
but I am getting line artifacts in the output.

I was not able to spot the error even after going over
the code many times. Please have a look at code and
suggest changes.

Thanks,
Nayan.
