v1.10.0

Added

• Reset EXIF orientation — new Images menu entry and ImageViewer toolbar button (Reset EXIF orientation) that sets the EXIF Orientation tag to 1 (normal) without rotating pixels. Disabled when the selected image has no orientation tag. Undoable (("reset_exif", [(path, orig_orient)])); status bar shows the count of affected files; undo restores the original tag value.
• exif_auto_rotate setting (default true) — new boolean config key; when false, thumbnails and the ImageViewer display images without applying the EXIF Orientation tag. Exposed in Settings → Catalog configuration… → Images as the "Apply EXIF rotation" checkbox. Changing the setting live reloads the current image in an open viewer via set_auto_rotate().
• F6 / F7 / F8 keyboard shortcuts for rotation — Rotate 90° CCW (F6), Rotate 180° (F7), Rotate 90° CW (F8) in the main window; entries added to the keyboard shortcuts dialog.
• X and Z as aliases in ImageViewer — X = Fit window (alias for 0), Z = Actual size / 1:1 (alias for 1); toolbar tooltips updated to show both keys.
• Ctrl+click in ImageViewer — zooms to the clicked point in CUSTOM mode (previously this was done via double-click).
• _sanitize_exif_for_dump() in image_ops.py — converts Undefined-typed EXIF tags stored as plain integers (seen with some camera firmware) to bytes before calling piexif.dump().

Changed

• load_qimage / load_pixmap — added auto_rotate parameter (default True); the Pillow path now calls ImageOps.exif_transpose() when auto_rotate=True; the QImageReader path uses setAutoTransform(auto_rotate).
• set_exif_orientation() — reads raw EXIF bytes via Pillow (img.info["exif"]) before calling piexif.load() to avoid failures on certain JPEG files; is a no-op when the file has no EXIF block; calls _sanitize_exif_for_dump() before piexif.dump().
• Double-click in ImageViewer — now centers the viewport on the clicked point instead of zooming to it.
• ImageViewer scroll centering — on mode switch (Fit / 1:1 / Width / Height) and on image load the viewport is now centered; proportional scroll preservation is restricted to CUSTOM zoom mode.
• tools/fix_po_dates.py → tools/fix_po_files.py — file renamed; make translate updated accordingly.
• ruff-pre-commit — updated from v0.15.15 to v0.15.17 in .pre-commit-config.yaml; frozen commit hash replaced with version tag.

Fixed

• Zoom step additive instead of multiplicative — zoom in/out now adds/subtracts the configured step in percentage points (e.g. 23% → 48% → 73% with a 25% step) instead of multiplying by a factor (which gave 23% → 29% → 36%).
• set_exif_orientation() crash on non-standard EXIF — piexif.dump() raised a type error when camera firmware had stored Undefined-typed values as integers instead of bytes; fixed by sanitizing with _sanitize_exif_for_dump() before dumping.
