Plan Measure v2.9.1

What's new

• Added Check scale so users can compare an existing scale against a second known distance and view the measured length, known length, signed absolute difference, and percentage difference without changing scales or existing measurements. (#225, #214)
• Added a Pages browser to the viewer dock: search page labels, jump to a physical page number with Go to page, and browse lazily loaded thumbnails of the visible rows; for large or slow-to-render PDFs, the current page still gets its thumbnail and Load previews loads the others on request. (#226, #213)
• Added a compact save status for open projects that confirms local saves, identifies saving failures and repair or conflict states, and provides quick access to editable .planmeasure backups containing the PDF and current project data. (#223, #215)

Improvements and fixes

• Improves wheel zoom with many measurements: annotations keep the previous zoom (and, when the whole page is visible, a cached bitmap) while the wheel is active, then re-plan once after an idle window scaled to the cost of each step. With 5,000 measurements it goes from 10 to 58 fps (3 to 53 fps at 4x CPU throttle); with 1,000 at 4x, from 12 to 58 fps. (#227)

Validation

• Automated tests, lint and production build passed.
• GitHub Pages deployment verified for dce9960.
• Workflow run.
