Paint.NET 4.0.17

What's new in this version:

- Added: "Fluid mouse input" option in Settings -> UI -> Troubleshooting. If you see major glitches while drawing, try disabling this
- Improved: Default brush size, font size, and corner radius size now scales with major DPI scaling levels (brush size of 2 at 100% scaling, brush size of 4 at 200% scaling, etc)
- Improved: Default image size now scales with major DPI scaling levels (800x600 at 100%, 1600x1200 at 200%, etc.)
- Improved performance and drawing latency by removing explicit calls to System.GC.Collect() except when low memory conditions are encountered
- Improved performance by greatly reducing object allocation amplification by reducing the concurrency level when using ConcurrentDictionary, and by removing WeakReference allocations in favor of direct GCHandle usage
- Improved: Performance and battery usage by ensuring animations always run at the monitor's actual refresh rate
- Improved (reduced) CPU usage when moving the mouse around the canvas
- Removed: "Hold Ctrl to hide handle" from the Text tool because it was not useful and caused lots of confusion
- Fixed: Various high-DPI fixes, including horrible looking mouse cursors caused by a bug in the latest .NET WinForms update
- Fixed: Gradient tool no longer applies dithering "outside" of the gradient (in areas that should have a solid color)
- Fixed: Very slow performance opening the Effects menu when lots of plugins are installed after installing the Windows 10 Creators Update
- Fixed: When cropping and then performing an undo, the scroll position was totally wrong
- Fixed a rendering glitch in the Save Configuration dialog (it would "wiggle")
- Fixed: At certain brush sizes, the brush indicator on the canvas had a visual glitch in it due to a bug in Direct2D
- Fixed: Text tool buttons for Bold, Italics, Underline were not localized for a few languages
- Fixed a rare crash in the taskbar thumbnails
- Fixed: Drawing with an aliased brush and opaque color (alpha=255) sometimes resulted in non-opaque pixels due to a bug in Direct2D's ID2D1RenderTarget::FillOpacityMask
- Fixed: "Olden" effect should no longer cause crashes (it still has some rendering artifacts due to its multithreading problems, however)
