Without looking at the code, it is probably a question about what's more
expensive: Checking _every_ surface's alpha-setting or rendering
invisible surfaces. (Maybe we should take a walk through the grid with a
modified client that counts surfaces...)

Checking for Alpha would put load on the CPU, unneccessary rendering put
load on the GPU.
