Paint.NET 4.3.3

What's new in this version:

- New: The app has been migrated to .NET 6, which has improved both rendering and startup performance
- New translation: Catalan (ca)
- New translation: Corsican (co)
- New translation: Thai (th)
- Changed: The /createMsi command for the installer has been removed. Instead, you can now download MSIs directly from the GitHub releases page.
- Improved various UI controls for Dark Theme, e.g. scrollbars (Win10 v1809+ only)
- Updated the bundled AvifFileType to v1.1.17.0, which updates the AOM version and fixes a crash when reading large EXIF blocks

Fixed:
- the way various UI controls look on Windows 11, e.g. buttons and drop-down lists
- the View -> Zoom to Window command when using the keyboard shortcut (Ctrl+B), which was resetting instead of toggling the zoom level
- Improved performance during the "extracting" stage of the installer by migrating away from Nullsoft Scriptable Installer System (NSIS)
- Reduced the download size on ARM64 by about 33%
- a rendering bug in the Dents and Polar Inversion effects
- a memory leak in the selection renderer that was consuming gigabytes of GPU memory, resulting in crashes
- some GDI object leaks, particularly with the Save Configuration dialog, which would eventually result in a crash
- a memory leak in Settings -> Tools
- an issue that was preventing new plugins from loading their native DLL dependencies as specified in their .deps.json file
- the app crashing after an effect plugin crashes when you choose to restart the app
- a crash while drawing a selection, right-clicking on the History window before releasing the left mouse button, and then clicking to redo a history entry
- a text rendering bug in some parts of the UI, mostly in Effects, as reported by @midora
- the "untitled:" file name argument prefix, which was preventing Window Clippings from being able to send screenshot
- some registry keys that were not being deleted during uninstall
- the PdnRepair utility on Windows 7
- some inconsistencies with the MSI as compared to v4.2.16 which were causing problems for some deployments
