Plus renamed setupViewport to setup[2|3]DViewport. Migrated mWindowRect to mWindowRectRaw, mVirtualWindowRect to mWindowRectScaled. Slowly updating getwindow/getworldview calls to new v2 variants as I run across them. Cleaned up ascent-related code in llmanip.cpp. Impostor update tweaks. Edgepatch water occlusion changes. (no patch flickering on edges of screen while moving camera)
