Thalyd's Partially Submerged

Adds a subtle bobbing animation while pawns cross water and visually hides part of the submerged pawn, depending on how deep the water is.

Downed pawns use the swimming pose even in shallow water. With Odyssey installed, an optional drowning setting (enabled by default) causes downed pawns in chest-deep water or swimmable deep-ocean tiles to suffer native vacuum exposure from lack of oxygen.

By default, swimming pawns cannot fire projectile weapons from chest-deep water, and both colonist and enemy AI seek non-submerged firing positions. This restriction can be disabled in the mod settings.

Corpses in shallow or deep water remain hidden. An optional "Mark drowned corpses" setting (disabled by default) reveals a textureless silhouette when the cursor is within 5 cells.

An optional accuracy setting (enabled by default) integrates submersion into RimWorld's native target-size calculation: partially submerged pawns are 10% harder to hit and pawns using the swimming pose are 25% harder to hit. This affects attacks against submerged pawns, not their own shooting accuracy.
