This commit pretty much reverts all the changes related on tile-ability of the fast gaussian blur. It's not tilable by definition and would almost always give you seams on the tile boundaries. Atmind already met the issue and tried to solve it by increasing some magic constant, which is pretty much likely simply made it so compositor switched to full-frame calculation in that particular .blend file. Fast gaussian is really not a production thing and need to be avoided. We're to improve speed of normal gaussian blur instead.
