Remarks
Applies a box blur to magenta pixels found in given texture represented by InOutPixels using non-background pixels, this creates a smear across the magenta/filled pixels.
This version is allowed to shrink the array to a single pixel if the entire output is monochrome. Params will be adjusted accordingly when this occurs.
