I changed the way of downsampling the image before adding the blur effect for the bloom.
Before doing this I could't use more than 4x downsampling without getting aliasing problems (the bloom startet 'flickering' when the camera was moving which doesn't look good at all)
...but with my new shader I'm able to use more downsampling without much quality loss: I tried it with 40x and It still looked good
(40x means dividing the X and Y resolution by 40 - so the actual size is only 1/1600 (0,39%) of the original image!)
Here's a screenshot how the bloom looks with 40x D.S.
...oh I almost forgot: @Rackscha: looks very good. great job!
