Subject: [PATCH] fix a bug where map becomes invisible (just sky) when the
 nearclip plane culls a portal, this bug was introduced by recent water shader
 rendering features (using an extra clip plane for culling, accidentally
 activated the view's nearclip plane as well, which culls portals
 accidentally)
