effects, filter-blur: Precalculated Kernel, Formatting, Rendering and more

Browse source 
Filter:
* Massively improved Rendering loop to reduce overhead and provide cleaner code.

Gaussian Blur:
* Added precalculated Kernels using Textures. Slightly reduced GPU load.
* Added basic attempt at a Nvidia o(n/2+1) gaussian blur implementation.
* Fix up LOD for texture sampling.

Box Blur:
* Halved loop count.
