Merging in file-move-merge ( QAR-649 )
Result of "svn merge -r 90669:90786 $tulla/file-move-merge ." 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
