The Gaussian blur kernel is an approximation of the normalized convolution
G(x,y) = H(x)I(y),
H(x) = exp(-x2/ (2s2)) / sqrt(2* pi*s2)
I(y) = exp(-y2/ (2t2)) / sqrt(2* pi*t2)

The SVGFEGaussianBlurElement object has these methods:
- setStdDeviation: Sets the standard deviation values used in calculating a Gaussian blur.
The SVGFEGaussianBlurElement object has these properties:
- height: Gets or sets the height of an element.
- in1: Identifies input for the given filter primitive.
- result: Provides a reference for the output result of a filter.
- stdDeviationX: Gets a value that indicates the standard deviation in the x-direction, used in calculating a Gaussian blur.
- stdDeviationY: Gets a value that indicates the standard deviation in the y-direction, used in calculating a Gaussian blur.
- width: Defines the width of an element.
- x: Gets or sets the x-coordinate value.
- y: Gets or sets the y-coordinate value.
