The BLI bicubic interpolation function with border boundary is wrong around edges. It returns zero, where interpolated values should exist. This is due to a wrong early exit condition, where only a 2x2 window is assumed instead of the 4x4 window considered by bicubic interpolation. To fix this, assume a 2 pixel region in the early exit condition for both directions. Pull Request: https://projects.blender.org/blender/blender/pulls/131320
