Creates a pinch distortion of the image
radius: The radius from the center to apply the distortion
center: The center of the image (in normalized coordinates from 0 - 1.0) about which to distort)
scale: The amount of distortion to apply, from -2.0 to 2.0
Applies a pixellation effect on an image or video
fractionalWidthOfAPixel: How large the pixels are, as a fraction of the width and height of the image (0.0 - 1.0)
Applies a pixellation effect on an image or video in a spiral
fractionalWidthOfAPixel: How large the pixels are, as a fraction of the width and height of the image (0.0 - 1.0)
center: The point that the polar pixellization will begin at and spiral around.
Breaks an image up into colored dots within a regular grid
fractionalWidthOfAPixel: How large the dots are, as a fraction of the width and height of the image (0.0 - 1.0)
dotScaling: What fraction of each grid space is taken up by a dot, from 0.0 to 1.0.
