* Creates an image filter that samples a region. If the sample is inside the
* region the alpha of the image is boosted up to a threshold value. If it is
* outside the region then the alpha is decreased to the threshold value.
* The 0,0 point of the region corresponds to the upper left corner of the
* source image.
