Description

When blurring a predominantly dark or black image, the right side of the image has a pronounced white faded edge. Not sure if there's some way to render this off image or change the color of the transformation.

Research direction
Investigate the blur algorithm used in Blear, likely in a view controller or image processing class. Look for how the blur is applied and clipped. Check if there is an edge extension mode causing the white fade. Review any existing tests or comments related to this issue.
