Blur, sharpen, repeat

I added standard blur and sharpen functions to ImageProcessing today. The blur function uses standard Gaussian kernel convolution with the image. The sharp function employs an unsharp mask technique which uses the Gaussian blur function.

I'm not a big fan of Sourceforge, and I'm not entirely sure how they calculate project rankings, but mine has apparently climbed the ladder about 35000 steps to somewhere in the mid-2000s. Just in case this means people are interested in using/trying the library, I have re-prioritized project documentation as most important. You (meaning the 0 people who read this blog) should see at least javadocs in the next day or two.
