A surface blur filter based on a simplified version Porikli's O(1) bilateral filter.
Unfortunately due to the nature of the algorithm memory overheads can be severe. This filter uses a tile based implementation, which limits overheads to about 64mb.
On the plus side it is reasonably fast and scales well with filter radius.
When installed it should appear under filters->blur->simple bilateral
