1. the aliasing problem can be fixed simply by making the unbloomed parts invisible, and making the bloomed parts very blurred.

2. you never have to "reset" the bmap, you just keep the same global bmap thruout the game, and if you want to turn bloom off you just make the quad invis. I might have to double check to see if that part works properly, but even if it did there is still a way around it. i gaurentee it.
