Detailed Description
Note: This QML type is under development and is subject to change.
A convolution filter is most commonly used to apply a blur effect to an image although the exact effect will depend on the kernel set.
A typical blur is achieved by applying a Gaussian kernel with a large sample size and deviation. Increasing the sample size and deviation, repeat applications, and reducing the size of the input image can all increase the amount of blur applied.

The convolution kernel to apply to a FilteredImage.
Kernels can be constructed using the Kernel singleton.
