Paint.NET 3.5.9

- Improved: The "Auto-detect" bit-depth setting for PNG, BMP, and TGA now also determines which bit-depth to use based on which one produces the smallest file size, as well as which ones can save the image without losing fidelity.
- Improved: You can now use Ctrl+0 as a shortcut key for View -> Actual Size, in addition to Ctrl+Shift+A and Ctrl+Alt+0.
- Fixed: Some text in the DirectDraw Surface (DDS) Save Configuration UI was not being loaded.
- Fixed: Some DirectDraw Surface (DDS) files authored with other software (e.g. Unreal 2004) could not be loaded.
- Fixed: In some rare circumstances, clicking on the Save button in the toolbar would crash.
- Fixed: The Korean translation has been added back in, with the help of Bing machine translation to cover the few remaining strings that were untranslated.
