Floating Point Pixels with C# Half

[LaurentInSeattle]

My little photo app is currently using ImageSharp with a pixel type of RgbaVector. That's 4 Single floats for a total of 128 bits per pixel.

Since most image processing are 'happy' with half precision and dynamic range, is it possible to have a pixel type as a Vector of Half floats ? This would drastically cut memory requirements for large images provided by modern DSLR's.

Ideally it should work exactly like RgbaVector providing R G B properties as C# half instead of float.
