Chunk generator performance survey

[xoft]

You might not believe it, but I have considered that as soon as I started writing the new generator architecture. I didn't know anything about GPU programming at that time, so I did a little research, and the results are not good: There is no good standard that would be generally compatible with every gfx card. CUDA only works with nVidia cards and ATI has some other API. Now, we want to run on other devices, too - typically, internet servers in ISP server-housing don't have gfx cards at all. Raspberry Pi has a gfx chip, but doesn't provide the programming API. And so forth. So there's just no way to make this solution universal. Hence, it's not worth writing (yet).

I think the overall performance is good enough for now, so that we don't need to go this way immediately.
