The original BMP_{1..4}_{N,S,E,W,NE,NW,SE,SW,EN,ES,WN,WS}.png tiles were
very noisy low-quality checkerboard patterns. They are now redrawn as
hand-styled pixel-art bush/hedge tiles:
- 5-color per-theme palette (deep shadow, dark, mid, light, highlight)
- irregular wall/passage boundary with natural erosion
- shaded interior (darker in the center = depth)
- scattered leaf clusters and highlights
- kept 32x32 resolution and engine transparent-gray convention
A new generator tool is added at tools/redraw_walls.py. Run it again
with python3 tools/redraw_walls.py to regenerate the tiles if you want
to iterate on the style or palettes.
- Added `image_clean.png` to the output directory for the clean image representation.
- Added `image_clean_preview.png` for the preview of the clean image.
- Introduced `image_svg_clean.png` for the SVG clean image representation.
