Hey v71, that isn't exactly the issue. Thanks for the reply! I know beforehand they are coincident, this is 100% certain so no need to check. However as you can see in the image, the rendering algorithm doesn't use the same pixel set in the common region which is my problem. I settled down for the "diamond exit" algorithm which deals with that nicely, but I had to implement it myself.

The best one is currently http://www.gameplay3d.org

I would install a game on my computer, of course, and I would also download a game in the browser, no issues with that. But, when I do run the game on my PC or in the browser a message comes up saying "You need to install XYZ" my experience will be ruined and so I would remove the game right away. Usability is a very important factor for me. Of course I would play Unity stuff if the plugin was included in the browser, this makes it easier for me, the user, to play the game. As a developer, I am aware of alternative technologies -- WebGL, Flash with Stage3D -- which won't prompt me for additional installations and thus showing such a message is a major usability breach. It's like stating: "I won't go to the local bakery for some bread, I'll travel 50 km instead to get absolutely the same thing". It's why people use browsers in the first place, they make things easier. If I want to see an installer I won't play a browser, but a normal desktop game. I repeat again I'm well aware of the advantages the plugin provides.

This has nothing to do with the discussion. I don't agree or use everything the browser provides, but some things are rather useful.

Never installed and I don't plan to. I consider Unity to be a great framework, the 3D variant of Flash in every way, but to install another huge plugin? Won't happen for sure. I am not a great HTML5 / WebGL fan, don't get me wrong, but why installing a huge plugin when Chrome already features an embedded Flash player with full support for Stage3D? Why Unity won't utilize that? Asking the users to install something 5 minutes before actually playing a game is in my eyes a serious breach of usability.

Yes, rompa68 is right, use gaps between the individual sprites, most sprite packers offer you to do it automatically. Linear filtering is always a problem with scaling textures from spritesheets, try to use nearest as much as possible.
