Classes
struct	pulp::timeline_editor::ProjectedHitCandidate
	One timeline item after a front-end projects it into pixel space. More...
struct	pulp::timeline_editor::ProjectedHit
	The identity and region selected from a projected candidate set. More...

Namespaces
namespace	pulp
namespace	pulp::timeline_editor
	ScriptedUiHost is a SequencerUiHost whose playhead is written by the caller instead of an engine, and which keeps what a view emitted so a test can read it back.
namespace	pulp::timeline_editor::hit_test_detail

Enumerations
enum class	pulp::timeline_editor::ProjectedHitRegion : std::uint8_t { pulp::timeline_editor::ProjectedHitRegion::Body , pulp::timeline_editor::ProjectedHitRegion::LeadingEdge , pulp::timeline_editor::ProjectedHitRegion::TrailingEdge }
	The horizontal part of a projected item selected by a hit test. More...

std::optional< ProjectedHit >	pulp::timeline_editor::hit_test_projected_items (std::span< const ProjectedHitCandidate > back_to_front, float x_px, float y_px, float tolerance_px) noexcept
	Selects one projected timeline item using already-resolved pixel tolerance.
