What is the purpose of the "PreviousTexture" mentioned in the wiki?
http://sourceforge.net/apps/mediawiki/c ... el_Shaders

It seems to be exactly the same as "BackgroundTexture" when it is the first effect, and exactly the same as "ForegroundTexture", when any effects come before it.

Is it just so you can make effects that work on both the background and the foreground depending on its position in the effect chain?
