…S LUT. Extract TextureMapping/Contoning/Offset/Remap/ImportedTexture and ColorSolver vendors from OrcaSlicer-ImageMap @ 9254838. Track lut_wide.png.c with Git LFS. Register six texture_mapping_* keys only; leave paint_depth_* untouched. Co-authored-by: aceRage <aceRage@users.noreply.github.com>
Print apply loads texture_mapping_definitions, ToolOrdering resolves virtual zone IDs, and MMS nests TM outer-wall width around the Ultra paint-depth clamp. LayerRegion side modulation and Contoning gates live in LayerRegionTextureMapping; Fill gets a Contoning schedule driver rather than ImageMap's full geometry dump.

try_make_texture_mapping_perimeters is a free function, so *this leftovers from the ImageMap member extract would not compile. Fill now keys top-surface TM off solid_infill_filament, make_fills matches ImageMap's 5-arg cancel+cache form, and Contoning tests seed filament colours.

Emit texture/Contoning-aware extrusion volume and seam-hiding from GCode.cpp, round-trip texture_mapping_* plus imported atlas through bbs_3mf, and wire CutUtils Remap for simplify/cut. GLTF import is an unsupported stub. No Plater/gizmo UI. Co-authored-by: aceRage <aceRage@users.noreply.github.com>
Keep raw-atlas/RGBA 3MF restore even if imported UV counts do not match, write atlas sidecars without requiring print config, and add tests for virtual filament IDs, texture_mapping_color, and CutUtils remap. Co-authored-by: aceRage <aceRage@users.noreply.github.com>
