With Resize on, the note that says how much the rounding stretches the
picture came and went every few pixels of a drag, and each time the picture
area and the rows under it jumped by a line.
- No note appears or changes while a pointer is down. A note the drag makes
untrue goes away, and the note for the new size comes once, 0.2 s after
the release. A click, a typed number or a new picture still shows its
note at once; a run of arrow clicks or a held arrow key shows the first
value and the last.
- The note has a line of its own that is there whenever Resize is on, with
text or empty, so a note that comes or goes moves nothing. The Even out
button no longer makes that line a pixel taller.
- The size line only grows while you drag: a step that comes and goes
("round to 8") no longer wraps it in and out.
- The full editor's size box and status panel show the same settled note,
and the status panel keeps its height mid-drag.
The image node and both video nodes share this code. Even out now works its
padding out at the click, because the note can be a moment behind the values.
