+- **The video clip's IN handle always drags.** On Video Crop + Rotate + Pad
+  (Clip), a Length as long as the clip or longer used to lock IN, and the
+  only way to trim the start was to turn Length off. Now IN drags anyway:
+  the Length then only caps the clip, and the clip's own end is OUT. A
+  Length shorter than the clip works as before.
