Module scroll 

Scroll model

Repose separates visual scroll containers from scroll state.

This file implements scroll composables (wrappers that attach scroll bindings as modifiers). The actual scroll state types live in repose_core::scroll.

Velocities are expressed in px/sec and integrated with dt, so behavior is frame-rate independent.

Structs

HorizontalScrollState

X-only state

ScrollPhysics

Handles velocity estimation from input deltas, frame-rate-independent exponential decay, edge snapping, and animation state tracking.

ScrollState

Inertial scroll state (single axis Y).

ScrollStateXY

2D state

Functions

HorizontalScrollArea

Horizontal scroll container with inertia.

ScrollArea

Scroll container with inertia, like verticalScroll.

ScrollAreaXY

Two-axis scroll container with inertia.

remember_horizontal_scroll_state

remember_scroll_state

Remembered ScrollState (requires unique key).
