[FEATURE] Image view that supports shaders/filters/effects

[mattleibow]

Is your feature request related to a problem? Please describe.

It would be great to be able to leverage the power and flexibility of SkiaSharp to easily apply affects and filters to images.

Describe the solution you'd like

I would like to be able to apply effects to images in my XAML:

<SKImageViewSource="{Binding OriginalImage}" Aspect="AspectFit">
    <SKImageView.Filters>
        <SKHighContrastImageViewFilter Sigma="2" Style="InvertBrightness" />
        <SKBlurImageViewFilter Sigma="2" />
    </SKImageView.Filters>
</SKImageView>

Describe alternatives you've considered

All this can currently be done inside pure C# code, but often a blurred image is a lot of work for something so simple.
