Sequencer: Add gaussian blur effect

Currently this gaussian blur implementation accumulates values in the
square kernel rather that doing X direction and then Y direction because
of the lack of using multiple-staged filters.

Once we can we'll implement a way to apply filter as multiple stages we
can optimize hell of a lot in here.

Another thing we can do is to use SSE2 instructions here.
