Research direction
The issue requests adding custom shape (circle, contour) and fill color control for pixelation blurring. Start by reviewing existing pixelation implementation in Jimp's source code, likely in files related to blur and color effects. Check comments in the issue for additional context. Evaluate how to extend the pixelation plugin to accept shape and color parameters. Consider whether to use canvas APIs or pure pixel manipulation.
