q1: Too much light with multi-light-bounce and splitturb (2.0.0alpha4)

[maikmerten]

When activating lit water surfaces with _splitturb 1 (seems to be the default) and doing multiple light-bounces (e.g. _bounce 3), water seems to bounce around too much light.

To exaggerate, here's a screenshot with 10 bounces:

_bounce 1:

_bounce 2:

_bounce 3:

When setting _splitturb 0 in the worldspawn keys, lighting is back to normal (but then water is not lit, of course).
