Blockbench Texturing

This handles texture creation and painting in Blockbench through MCP tools. You get brush painting with configurable size, softness, and opacity, bucket fills with tolerance control, shape drawing for rectangles and ellipses, and gradient application. It covers layer management for non-destructive editing, selection tools with feathering, and UV mapping utilities including auto-unwrap for meshes. The workflow examples are practical, like building a Minecraft skin with base colors and detail painting. Mirror painting and pixel perfect modes make it solid for symmetrical pixel art. If you're texturing 3D models in Blockbench and want programmatic control over the paint tools instead of clicking around manually, this gives you the full painting API.
