[gscan2pdf-announce] scantpaper v4.0.3 released

[Jeff <jf...@po...>]

Changes compared to v4.0.2:

* **File → Import hOCR…** applies a saved hOCR file to the selected
   pages or all pages. Pages are matched in order and each page box must
   match the target page's pixel size within one pixel; only the text
   layer is replaced, as one undo step. A rejected import shows the page
   count, dimensions, or parse reason instead of an empty error message.
   Images and annotations are untouched. Pages without OCR are now
   included in a multi-page hOCR save as empty page boxes, so they keep
   their position and round-trip as pages with no text. This lets
   corrected OCR be restored after rebuilding a session from the original
   images.
* Restoring a crashed session now copies its snapshot into the current
   temporary session and removes the snapshot once the pages are
   available. A restored session is therefore removed on a normal exit
   instead of being offered again on every start. A failed restore leaves
   the snapshot intact.
* The crashed-session picker now offers **Discard** as well as
   **Restore** and **Cancel**. **File → Open crashed session** opens the
   same picker instead of a folder chooser that could not select the
   `.sdb` file. Sessions in use by another instance are skipped without
   blocking startup.
* The Messages dialog no longer clips its global "Don't show this
   message again" label and checkbox. The control now sits in a fixed row
   below the message list and above the buttons, so it stays visible
   however many messages there are, and the list uses the dialog's spare
   height while each message row keeps its natural height. The columns
   and rows are now separated by the same spacing used elsewhere in the
   dialog, so headers, message cells, and hide checkboxes no longer
   touch. A message without a page number leaves its Page cell empty
   instead of showing "None".
* Closing the Messages dialog with Escape or the window close control
   now returns to the caller instead of leaving it waiting. Message text
   is a selectable label rather than a focusable text view, which avoids
   a segfault in the GTK4 IBus input-method module when the dialog is
   closed.
* The text-layer and annotation canvases now follow the active Pan,
   Select or Select & Pan tool, so each tool behaves the same in the
   image and in a layer pane. Pan pans with the left button, Select
   selects with the left button, and Select & Pan selects with the left
   button and pans with the middle button. The middle button no longer
   pans while Pan or Select is active, and the pointer shows a grab hand
   or crosshair to match the active tool.
* Focusing a slice while editing the text or annotation layer now zooms
   so its line is drawn at a consistent, comfortable reading size instead
   of a fixed fraction of the pane. Short and long words from the same
   line look alike, and a long word still fits with a margin around it. A
   **Focus zoom** control beside the navigation buttons adjusts that size
   in 5% steps from 50% to 200% (default 100%); it applies live,
   **Reset** returns it to 100%, and the chosen level is remembered
   across restarts for both layers.
* The control bar below the text or annotation editor now always keeps
   only its minimum height. At startup the scanner-detection progress bar
   disappears once detection finishes, and the space it released used to
   enlarge the edit bar; the view now keeps that space. In a vertical
   split the image and the layer canvas each take half of it.
* A word added manually inside an existing OCR paragraph's bounding box,
   but outside its lines, is now included in the saved PDF's searchable
   text layer. The exporter gives such words the synthetic OCR line the
   PDF renderer requires, so words added after importing an old hOCR
   layer no longer disappear from the output.
* **Scan** now remembers a click made while scan options are still being
   applied and starts the scan as soon as the apply finishes, instead of
   dropping the click and making the user click again. The focus-zoom
   popover also closes when its layer control bar is hidden, so switching
   layers and coming back no longer needs an extra click to open it.
* Pressing or dragging in the image view while no page is displayed no
   longer raises a `TypeError`. Select and Select & Pan now ignore input
   with no image and leave no partial gesture, so the first selection
   after a page appears starts where the user pressed.
* The layer control bar now appears and disappears immediately with its
   layer, without waiting for a window resize. It has a fixed height
   instead of sitting behind a draggable divider, so the image or split
   view always keeps all the remaining vertical space and returning to
   the Image tab reclaims the bar's space at once.
* **Device blacklist** now works as its hint says. The value is matched
   case-insensitively against the label shown in the Device list and the
   backend name, so `CameraA` hides a camera that SANE offers as a
   scanner. A **Blacklist this device** button hides the selected device
   in one click, cached device lists are filtered without a rescan, and a
   pattern that hides every device reports that no devices were found
   instead of crashing. The preference now explains what it matches and
   gives an example.
* The image selection can now be cleared explicitly with **View → Clear
   image selection**, a toolbar button next to the selection tools, or
   Escape. Clearing removes the rectangle instead of collapsing it to a
   zero-size selection, so **Add** is disabled and **Crop** reports no
   region; navigating to another page keeps it cleared.
