ProteinMotion 0.12.0 — cutaways, depth tunnels, and threading

ProteinMotion 0.12.0 adds cutaways, depth tunnels, and threading animations.

python -m pip install --upgrade proteinmotion

• Cutaways. Reveal(camera, region) opens a window onto a hidden selection that follows the camera; Conceal(camera) closes it. Atoms are hidden for display only; nothing moves. Molecular surfaces are carved down to the selection.
• Depth tunnels. shape="tunnel" drills a tunnel fixed to the molecule, with a ring every 5 Å from the surface, to show how deep a selection lies. camera.animate.depth_cue(...) eases the distance fog, and camera.clearest_view(region) finds the least-occluded view.
• Threading. Thread(protein, camera) flies a wire in for each chain from its own side of the screen; each wire enters at the C terminus, traces the backbone to the N terminus, and the protein fades in. Unthread reverses it. Options include stagger, easing, and glowing tips with glow, glow_color, and glow_brightness.

Cutaways, tunnels, and the glow are drawn by the native renderer; EEVEE renders the full molecule and plain wires.

Validation: 205 tests passed on Apple silicon with EEVEE enabled; five NVIDIA-only tests were skipped. A fresh installation of the release wheel passed dependency, CLI, packaged-resource, starter-scene, and skill checks, then rendered and decoded a Metal/VideoToolbox movie.
