Massive deferred update...

Browse Source 
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)
