v2.10.2

Fixed

• Track boxes drawn over the grid lines on high-DPI screens: the v2.10.1 change made the misalignment worse. Scaling each layout component separately (col * int(cellSize * scale)) accumulated rounding errors, so on fractional scale factors (e.g. 1.12, 1.37, 1.45, 1.74 — typical of a 2560x1440 macOS display) the green/red track boxes overlapped the grid lines.
  • prepareTracksPosition() now computes each box from the same rounded grid-line coordinates used by createTrackGrid() and centers it inside the cell interior.
  • Verified numerically for every scale factor from 1.00 to 2.99, and with real screenshots of a simulated read at scales 0.75, 1.37, 1.45, 1.48 (3440x1440), 2.66 (3840x2160) and 3.54 (5120x2880): no box touches the grid, max 1px centering difference.
• Tiny fonts after changing language: changeLanguage() reset the application font to 9pt, discarding the high-DPI scaling (on macOS 1pt = 1px, so text dropped to 9px). For Greek/Russian/Ukrainian/Japanese/Chinese the font always ended up at 8pt (also at startup for el/ru/uk), and the diagnostic font could shrink to 2px. Fonts are now always sized in pixels and scaled with the UI scale factor.
• Unscaled fonts when the Topaz font fails to load: the scale factor is now computed and the fallback system font is scaled too.

Changed

• macOS scale factor: the size tier is now chosen from the full logical screen size instead of the area left free by the menu bar and the Dock, so a Mac no longer falls into a smaller tier than the same screen on Windows/Linux (e.g. 2560x1440 with the Dock: 1.37 → 1.48; 1920x1080: 1.05 → 1.15).
• The window is now guaranteed to fit the available screen area on every platform.
• Menu bar and menus scale their item padding (items no longer touch each other at 4K).
• Check boxes scale their indicator size and spacing together with the text.
• The scale factor auto-detection is now a single shared function (MainWindow::calculateScaleFactor()) used by both main.cpp and MainWindow.
• Removed a duplicated QDir::setCurrent() call in the macOS startup code.
