Citizen/animgraph: airborne side selector
(During the post-jumping airborne state, the legs will now match the weapon pose; that is to say, which leg should be forward, if either. This is implemented thanks to Tags on Single Frame nodes)
More big changes to the animgraph compositing structure
Additive attacks, procedural hit reaction tweaks, proper pelvis delta compositing in which upper body motion doesn't get doubled up, fixed helper bones getting jittery, head look chain is now part of weapon branches, etc.
Upper body compositing now switches between 3 different weightlists based on a variety of conditional checks
This allows "action" animations (attacking, reloading) to properly fully take over the upper body, while simply running will let more of the underlying spine movement through, and being idle will let more of the idle noise through.
Citizen animgraph updates with massive improvements
Conditional aim *and* IK disables on all holdtypes
New damping parameters on a new look/aim setup for weapon holdtypes
Separate damping and new look chains when not wielding a weapon
Weapon gestures now also composite a pelvis-only additive component
(and probably more that I forgot)
Merge branch 'master' of sbox
Duck being an analog/float input is now properly handled, your equipped weapon has no more weird offsets from where you're actually aiming, and weapon gestures can disable aim chains as well as IK (though somewhat inelegantly for now)
Fixed jump sometimes playing the fall animation instead of jump
(This could happen if you jumped right after landing in a very small time window. The state machine needed some more conditional checks.)
