Timeline blueprint is glitched when the hit object has negative duration.
Negative duration is unwanted anyways so placement implementation is fixed instead of supporting it in timline blueprint.
No "clipping" occur anymore for vertex positions. Instead, clipping may occur when the path is converted to a slider.
Add tests for automatic slider velocity change.
Tests have started to output too much log content, causing viewing CI
failures to be painfully impossible. Roll back for now.

use filter.
