Simplification filters for removing fine details from textures

Purpose

• Remove texture artifacts (scales, fur, feathers, noise)
• Preserve edges and broad color zones
• Prepare textures for cleaner palettization

Scope

• In-scope: Edge-preserving texture smoothing
• Out-of-scope: Color adjustment, resizing, format conversion

Entrypoints

• simplify_texture(image, enabled, d, sigma_color, sigma_space) - Apply bilateral filter

Dependencies

• External: opencv-python, PIL, numpy
