Summary0002435: Add support for a second texture in custom Shader Brushes
DescriptionRight now only the texture corresponding to the Image associated to the brush can be samples in a custom shader.

We should extend this to, at least, support a secondary texture. Note that this texture will use the same UV coordinates than the first one.
TagsNo tags attached.

Added a SetTexture method to BrushShader, this way, new texture dependency properties can be created in new brushes.

public static readonly DependencyProperty TextureProperty = DependencyProperty.Register(
    "Texture", typeof(ImageSource), typeof(NoiseBrush), new PropertyMetadata(null, OnTextureChanged));

private static void OnTextureChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    if (d is NoiseBrush brush)
        brush.SetTexture((ImageSource)e.NewValue, 0);

The extra texture is passed in the t4 register:

Texture2D input: register(t4);
SamplerState inputSampler: register(s4);

half4 GetCustomPattern(in In i)
    return input.Sample(inputSampler, i.uv0);
