Detailed Description

Sets a clip's clip-start / loop-start / loop-end to absolute content positions, undoably.

The command is immutable once constructed: it captures the clip's current state as before_ at construction and applies the given target on redo(). There is deliberately no "update the target while on the stack" pathway — live dragging is handled by mutating the clip directly during the gesture and constructing (and pushing) a single command at the end (see actions::ClipOperator).

The clip is held by a reference-counted TypedUuidReference, so it stays alive while the command is on the undo stack.

void zrythm::commands::SetClipLoopPointsCommand::applyToClip ( structure::arrangement::Clip & clip, dsp::ContentTick clip_start, dsp::ContentTick loop_start, dsp::ContentTick loop_end )

static

Apply a loop-points target to clip directly: length-tracking is disabled, the three positions are written atomically (no per-set clamping via Clip::set_loop_range), and tracking is re-engaged when the result is the default range (0, 0, length).

Used by redo() and by ClipOperator's live drag preview so the committed state always matches the preview.
