68d982035f Add bicubic-5-taps and hermite shaders 
- Two standalone fast shaders.

* Hermite was never explicitly available, so I think it deserves a place. It's a slightly softer quilez shader.

Repo reorg: edge smoothing, interpolation, and pixel art scaling (#469) 
* Move initial batch of shaders and presets to smoothing subdirectory

* Rename smoothing to edge enhancement

* Move cubic and windowed into interpolation

* Fix some presets

* Fix rest of presets

* Rename edge-enhancement to edge-smoothing

* Move pixel art scalers into separate directory separate from 'interpolation'

* Flatten interpolation/cubic into interpolation/

5fc0d5396b Add uniform-nearest shader 
Features:
- produces nearest neighbor look with fractional scales.
- uses texture AA shader code.
- uses hotizontal subpixel scaling.
- due to different pixel sizes, moving sprites change dimension if nearest neighbor is used with fractional scaling. This looks unsteady. This shader uniforms pixel dimensions. Output looks much quieter.
