Implement resampling?

[doko-desuka]

I noticed that the image result has a lot of jagged lines (aliasing). Have you considered implementing a resampling function? (bicubic, lanczos etc.)

Just pushed bilinear interpolation. This program uses OpenGL shaders to perform the conversion. OpenGL textures can automatically resample using bilinear interpolation, but not bicubic. Hopefully this helps!
