compositing test with filtering 2 icon png download

A compositing idea on how to solve the 1 px rendering gap issue between touching objects. On the top there are 128 separate squares next to eachother, showing the issue by regular rendering/compositing. On the bottom there is one object with a loooong filter. Each of the squares are pulled in with the image filter primitive and using arithmetic composite on them where the alpha values always add up to opaque in between. Squares are now rotated 30° so they definitely are not aligned to the rendering pixel grid, to enhance the effectiveness of the filter.
