Linear Box Blur abuses the fact that with Linear Sampling we can sample up to four adjacent texels at the same time and get a correct result for Box Blur back. Using this the total number of sample for Box Blur is reduced by n, making the total either n+1 (Even Radius) or n (Odd Radius). Additionally all blur effect files have been merged into a single blur.effect file to reduce the time required to change a single parameter name. New blur effects should be added as a new technique instead of as a new effect file. See Also: #21 Blur Quality
