Hey there! FilterJS became a part of my graduate work, and this change adds to it a bunch of non-linear filters that aim to make image quality better.

New blocks include:

• Fast Sharpen — a 3x3 pixel filter that has options for a much powerful sharpening, and for suppressing overshooting that generates artifacts on images in other programs;
• Adaptive Sharpen — works perfectly on resized images, this filter makes blurred lines crisper while remaining already sharp edges untouched;
• Median & Percentile — a traditional median filter with an option to set priority for lighter (or darker) colors;
• Smart Blur — this one should be similar to Adobe Photoshop users, though its scientific name is Bilateral filter. This one performs a Gaussian blur on an image but preserves contrasting features and sharp objects. Useful for noise suppression as well!
• Nearest Neighbor filter — this one is somewhat similar to Median filter, as it is used for noise removal, too, but Nearest Neighbor filter preserves the form of edges and makes an image look more… cartoonish.

And a small bonus:

• Skin colors — generates a black-and-white mask from skin tones.

All these blocks can be found in the "Processing" category.

This release also fixes an issue with subsequent image exports.

Happy filtering!
