IZY Weapons x Custom Avatars Compatibility

IZY Classic (All in One) is now supported. 1.0.0 worked only with the New Weapon Pack. Classic uses a completely different arm rig and needed most of its handling written from scratch. Note the two packs still cannot be installed at the same time.
NEW - the arms are matched to each weapon automatically. 1.0.0 was tuned by hand and only really fitted the weapons it had been tuned against. The shoulder, upper arm, elbow and wrist are now measured from the weapon's own rig every time you draw it, so a weapon nobody has ever tuned still comes out right. Verified across eight avatars and both packs.
NEW - arm trim. Your avatar's arm is cut off at the point where the weapon's own arm ends, so no shoulder or torso geometry appears in view. The cut ring is measured from the pack's arm mesh, so it lines up on any avatar rather than sitting at a fixed distance.
NEW - move a whole arm. For the case where one hand sits on its grip correctly and the other floats short of it - usually the off hand on a two-handed weapon, because your avatar's hands are smaller than the arms the weapon was drawn for. ARMS tab -> WHOLE ARM slides that arm bodily until the gap closes, changing nothing about its shape: every joint angle, the hand pose and the finger curl stay exactly as they were. Per side, so the good hand is never disturbed, and saved against the weapon in your hands rather than the avatar, because a gap belongs to one weapon.
About the weapon move/rotate feature I announced: it turned out not to work, and the above replaced it. The pack's arm rig lives inside the weapon, so moving the weapon moves your hands with it and the gap never actually closes. Moving the ARM instead does close it, and that is what shipped.
NEW - finger curl and finger girth, per finger, per hand. Curl closes a finger onto the grip; girth thickens a finger without lengthening it. Reaching a grip no longer means inflating the whole hand.
NEW - elbow roll, for a forearm that comes out twisted between the w…
