Research direction
Investigate current image manipulation functions in Jimp to understand pixel format. Propose and implement a shift function that takes parameters for direction (horizontal/vertical), amount (pixels, percentage, or phase). Consider edge cases like wrapping vs. cropping. Look at similar libraries for reference.
