Moving a rectangle, an oval or any other comment showed only its blue
frame going, the shape staying where it was until release. The comment is
now rendered alone once as the drag starts (Document::comment_layer: a
read-only copy with only that comment, no page content) and laid over the
page where it goes; the page beneath keeps showing it where it was until
the move is applied, as a CAD program's move does. Rendering the page
without it would cost a whole page's render at every drag on a heavy plan.
Stamps and Fill & Sign marks keep their own layers. annot: isolate_annotations
for several comments of a page, so a group can be drawn together.

The locked-reply check in delete_annotation also reached stamp_preview
and signature_image, which only take the annotation off a copy to draw
the page beneath it: an unlocked stamp with a locked reply lost its drag
preview. They now use lift_annotation, which checks no locks.
The Comments panel's Delete (comment and reply menus) and the page's
context menu are greyed out while a reply below is locked
(comments::locked_below), rather than refusing after the click.

While a handle of a Fill & Sign line, check, cross, dot, typed signature
or comment stamp was dragged, only the selection frame followed the
pointer; the stamp kept its old size (or place) until release. Image
signatures already had a live layer. Every stamp now gets one: the page
without the stamp, and the stamp drawn alone on a transparent page,
whose pixels are stretched with the frame. Resizing a stamp only changes
its /Rect, which its appearance is stretched to fit, so the preview is
what the release produces.
- render: RenderConfig.transparent clears the page to transparent.
- annot: isolate_annotation leaves a page showing one annotation alone.
- engine: Document::stamp_preview builds the two read-only layers; the
page beneath gets the appearances drawn for comments without one.
- ui-egui: the signature drag layer covers every stamp, rendering the
stamp's own tile sharp at the current zoom.
