To play a clip at its real speed the user had to know its length,
work out the last whole frame by hand and then scroll far to the
right to set the end key. The timeline now does the sum, and it
zooms out far enough to see a long clip in one piece.
- The context menu of a Video time row gets "Video at 1x to its end
from frame N". It keys the playhead with the row's value there and
the last whole frame before the clip ends with the matching time.
- The start key turns linear and keys in between are removed. The
whole run is one undo step (KeyStraightRunCommand).
- The clip is the one the sprite wears at the playhead, also when
the texture is keyed in the same animation (rowVideoAt).
- The entry is greyed out for relative rows, without a video, while
the length is unknown, or when the playhead is already at the end.
- The status line names the result, e.g. "frame 572 shows 57.2 s of
57.27 s".
- The timeline zooms out to 0.02 px per frame instead of 4 px. The
ruler labels follow a 1-2-5 step without an upper limit.
Tests:
- Unit video-clock + timeline-view: 27 tests green, 8 new
- e2e 66 (atx, alone): ALL PASSED, 23 checks, 66l new
- Gate (atx): CHECK EXIT 0, 297 files, 4553 tests
- Counter-check: the command keeping the keys in between turns
exactly the command test red
