The following plugins need external files in order to function:

FFMpegPlugin.dll
	Generates thumbnails for video files. Needs ffprobe.exe and ffmpeg.exe in
	the Plugins directory. https://ffmpeg.org

ImageSorter.dll
	Provides sorting mode based on perceptive hash (using VGG or MobileNet; the
	latter preferred). Needs Plugins\lib\x86 (or x64): darknet_no_gpu.dll,
	pthreadGC2.dll, pthreadVC2.dll (these are bundled), as well as
	Plugins\cnn: mobileNetv2.* and vgg*.

Obtain required files from https://go.soletude.ca/stagsi/archive/extra

The following plugins work out of the box:

MagickPlugin.dll (needs the companion Magick.NET-Q8-AnyCPU.dll)
	Generates thumbnails for image files using ImageMagick/Magick.Net.
	Comprehensive but slow and memory-hungry. https://imagemagick.org
	https://github.com/dlemstra/Magick.NET

PsdPlugin.dll (needs the companion psd2pixels.dll)
	Generates thumbnails for Photoshop documents (PSD). Low footprint but
	doesn't handle certain documents well (especially PSDs saved in no
	compatibility mode). https://github.com/ipkn/psdlite

Svg2XamlPlugin.dll (needs the companion Svg2Xaml.dll)
	Generates thumbnails for vector SVG images. Known not to work on some SVGs.
	https://www.nuget.org/packages/Svg2Xaml/

TestSortPlugin.dll
	Acts as a sample plugin providing sorting based on EXIF datetime field.

TxtPlugin.dll
	Acts as a sample plugin generating thumbnails for plain text files (.txt).

WpfPlugin.dll
	Generates thumbnails for image files using native Net WPF capabilities.
	More efficient than ImageMagick but only handles popular formats.

XamlTunePlugin.dll (needs the companion XamlTune.dll)
	Generates thumbnails for vector SVG images. Generally works better than
	Svg2Xaml. https://www.nuget.org/packages/XamlTune
