!! 8) Horizontal mirror

It reverses  the images (what was on the left is now on the right side ...).
 
!! 9) Boxblur

This is a very interesting filter (and it gives some excellents results with the right values) as it can be used to make some blur backgrounds in an animation file. The value of the '''Blur strenght''' must not be too high and it has to be related to the value of the '''Blur ray'''.
For exemple, a blur ray value of 18 and a blur strenght value of  2 gives something which is really really blur, but it still remains somehow suitable, but a blur ray value of 18 and a blur strenght value of 10, gives something which is too blur. A blur ray value of 8 and a blur strenght of 4 gives a result which is blur but interesting.
