The page pointer has the pointer only where egui has the pages on top, and egui knows what
is drawn over them from the layers it met in the frame before. Dialogs are drawn after the
pages, so on the frame one opens egui has not met its layer yet. For that frame the pages
kept the pointer, and a press that landed then was theirs: a link's tip showed over the
dialog, and a click placed a stamp or followed a link under it. main's page_covered had
kept the link's tip and click off the page while a dialog was open, from a hand-kept list.
PagePointer::read now also takes whether a dialog is open: PdfCraftApp::modal_open, the
list the page press and the edge scroll already check, the Unlock prompt included. With one
open the pages see no pointer and no press, except a drag they already have, which goes on
to its release. The palette is not a dialog and the page beside it keeps its tools, so it
is left to egui's layers, from the frame after it opens.
Tests: tests/it/pointer.rs hovers a link and opens the Unlock prompt (no tip in that
frame), and clicks with the Stamp tool in the frame the prompt opens (no stamp). A
page_pointer unit test hides the pointer and a click under a dialog, and keeps a drag the
pages have until its release. With the fix reverted, all three fail.

A click on a check box or radio button focuses it, so Tab, Space and the arrows reach it
(#2223). The page hands the click to the field, and the field overlay toggles the box in
the same frame unless the click landed elsewhere. That check read hover_pos, which is None
on the frame egui reports a tap: egui-winit sends PointerGone with every touch release,
and winit reports Windows pen input as touch. So a finger or pen tap counted as a click
away. The focus closed and the toggle was dropped: a tap left a check box unticked and
unfocused, and a tap on a radio button selected nothing. The check now uses the overlay's
clicked_outside, which reads interact_pos, as the other field editors do.
Tests: touch_tap_ticks_a_check_box runs again. tests/it/editor_taps.rs taps a focused
check box and the other button of a focused radio group, each with a mouse click as the
control. Each checks that the focus stays and the tap toggles, and for the radio group that
the arrows still move within it. With the fix reverted, the three tap tests fail and the
controls pass.

The page view had no single reading of the pointer. About twenty page modules each
read egui's raw state (hover_pos, latest_pos, interact_pos, press_origin) and tested it
against an unclipped page rectangle. That state knows nothing of what is drawn over the
pages, and hover_pos is None on the frame a finger or a Windows pen lifts: egui-winit
sends PointerGone with every touch release, and winit reports Windows pen input as
touch. So a tap placed no stamp, followed no link and ticked no check box. A touch drag
of a comment never committed, and the next drag anywhere on the page moved the comment.
The Stamp crosshair showed on the command palette, on the quick bar and on the chrome
over a page scrolled under it, a link's tip floated over the Unlock prompt, and a
double-click on a dialog's backdrop selected the word under it.
canvas::document_area now reads one PagePointer per frame from the pages' content
widget (step 1 of the page pointer router in the cursor-handling review):
- pos: interact_pos, which keeps the position through a touch release, only while egui
has the pages under the pointer with nothing over them (contains_pointer, and the top
layer there is the pages', as the closed#2626 did) or while the pages hold a press.
- origin: where the held press began, also on the frame that brings both the press and
its release. This replaces the text layer's raw-event fallback (#2100).
- edges: the frame's primary presses and releases on the pages, in order.
It reaches the page modules through comments::PageCx and as an argument: the stamp
blocks, text layer, page press and link and comment hover in canvas.rs; comments and the
signature drag preview; forms and Prepare a form; Fill & Sign and the Sign area; crop,
marquee zoom, snapshot, camera and measure; redact and the Link tool; added content,
Edit text, images and objects. page_covered, a hand-kept list of what covers the pages
that missed the Unlock prompt, is gone. The pages' hover tip is click-through, as a
tooltip is, so a quick move onto it does not take the pointer off the link under it.
Tests: tests/it/support/input.rs sends pointer input in the frames the platform delivers
it in (a touch tap and drag, a click in one frame, a double-click). kittest otherwise
runs one frame per event, so the suite never saw a touch release. tests/it/pointer.rs
holds the review's probes and #2626's layer tests. With the fix reverted, the
tap (stamp, link, check box), touch drag, palette, quick bar, chrome, Unlock tip and
dialog double-click tests fail, and the mouse-click and one-frame-click controls pass.
The tip test fails with the tip interactable, and each page_pointer unit test fails
under a mutation of the part it pins. The probes for later steps stay ignored: the
link hand and the I-beam over other tools' targets (step 2), paragraph edges (step 3)
and Escape mid-drag (step 4). touch_tap_ticks_a_check_box is ignored until the
check box focus fix that follows: since #2223 a tap on a check box counts as a click away
from its focus.
tests/it/comments.rs: the multiline markup hover test (#3541) hovered a point below the
window on a page rotated 270 degrees, and its tip showed only because the hover was
tested against the page's whole rectangle. Its harness now zooms to 100 %, so every
rotation shows the whole page, and the hover helper asserts the point is on screen.
