light pass stats
make gscale 0..100
optional cubic scaling
make default cubic scaling sharper
tetraclip cleanups
fix tetraclip on gl_ClipVertex fallback
just get rid of tetrahedral shadowmaps since they provide no practical speedups
just remove inferred lighting since g-buffer scaling is a more reliable speed-up where necessary
clean some deferred light shader cruft
more effective AA movement masking
fix modelpreview shader
model alpha fix
bilateral upscale option for SSAO
allow smaa to function without depth or stencil
ssao shader fixes
SSAO shader fixes
use R8 format for tqaa movemask to allow less reducing by default
use R8 format for SSAO where applicable
slightly different quincunx pattern
fix tqaa mask scaling
fix GL extension typo
