Shaders reading back from adjacent/global tiles

@alexjc Really cool project indeed!!! I guess it's abandoned though?

I'd like to ask you, have you ever considered the problem of shaders that need to read back from tiles where the texel won't be the same but rather will be from adjacent tiles or even worse, from global tiles? For the case of adjacent tiles it seems you'd need to render the tiles with extra padding and then cropping those tiles when capturing... but for global ones I don't really know how you'd solve it :/

I'd like to hear your opinnion about this matter, I guess you've already considered this very problem when you were creating this kewl script ;)
