In-cloud fog: Strengthen effect when small view range is used

lhofhansl · paramat · commit 5045bdc6d814 · 2017-07-18T22:16:41.000+01:00
Ensure in-cloud fog is always stronger than outside-of-cloud-fog even when
using a small view range.
Also limit in-cloud fog range to a maximum of 32 nodes to keep it fairly
strong when using a large view range.
