Be careful of future merges involving changes to any of these moved files as SVN usually does the wrong thing:
newview/llglslshader.* -> llrender/llglslshader.*, llrender/llshadermgr.*, newview/llviewershadermgr.* (gets split into 3 separate files)
newview/llpostprocess.* -> llrender/llpostprocess.*
newview/llrendersphere.* -> llrender/llrendersphere.*
newview/llcubemap.* -> llrender/llcubemap.*
llwindow/llgl.* -> llrender/llgl.*
llwindow/llglstates.h -> llrender/llglstates.h
llwindow/llgltypes.h -> llrender/llgltypes.h
llwindow/llglheaders.h -> llrender/llglheaders.h
