Pixel Painter

Changelog 1.2.1 Added Aeronautics/Sable paint transfer support. Paint placed on unassembled blocks now carries over when the structure is assembled into an Aeronautics vehicle. Paint placed on an assembled Aeronautics vehicle now carries back over when the vehicle is disassembled into normal blocks. Added protection against ghost/floating paint during disassembly by only restoring paint onto real placed blocks. Fixed the target pixel preview on stairs, copycat slopes, and Aeronautics/Sable vehicles so the white ghost pixel lines up with the actual paint location. Improved preview targeting for multi-surface blocks, so the outline uses the exact surface being painted instead of floating above the intended face.
