confirmations.deleteAnnotation

"Delete this annotation?" — asked before the handle's Delete button, or Delete / Backspace, removes a selected annotation, drawing, text box, image, stamp or placed signature. Off by default, on purpose: the deletion can be undone, so the SDK removes it, says so in a toast and offers Undo — a question before every highlight teaches people to click through questions. Turn it on for a product whose users would rather be asked.
