TranslucentBucket :

- Added a translucent bucket that is rendered after the processors (usefull for shadows)
- For filters, rendering this bucket is a bit particular, so you can use the TranslucentBucketFilter to render the translucent bucket in the middle of the fillter stack (doc is comming up in the wiki)
- renamed Filter's preRender method to postQueue for consistancy with processors
- added translucent objects in TestPostWater, added a fire (particles) in test transparent shadows
