filter-blur: Allow applying Blur to a sub-region of the source only
...
The Blur Filter can now be applied to a region inside the source itself, the inverse of that region, and/or a feathered version of that region. This allows for easier scene setups where only some parts need to be blurred, but the rest can be left as is.
Fixes #12

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

filter-blur: Move effects to 'data/effects'
...
This should help reusing the same effect instead of having an effect per filter.
