Configure the linear interpolation of any sampler2D uniform

[gre]

linear interpolation can be defined on almost everything: textures, content and fbos.
so we should be able to define a disableLinearInterpolation: true prop on a GL.Uniform or attached in a {value, opts: { disableLinearInterpolation: true }} object, like it's already possible for ndarray in DOM impl: https://github.com/ProjectSeptemberInc/gl-react-dom/blob/601180581a461760f541ee459552df9b8d2c52ef/Examples/Simple/Colorify.js#L36 / https://github.com/ProjectSeptemberInc/gl-react-dom/blob/6e4b9f4a8eb0045977c643a4920651082cb36fcb/Examples/Tests/index.js#L102-L111

use case:
you have a HelloGL 2x2 and you want to scale up to 200x200 but without linear interpolation so you preserve the 4 pixels in the display

[gre]

This is now solved in gl-react v3 ! It's a complete rewrite.

• see release article: http://greweb.me/2016/12/gl-react-v3/
• see cookbook/api: https://gl-react-cookbook.surge.sh
• gl-react v3 is still in development. (hosted on: http://github.com/gre/gl-react )
• gl-react v2 is still the stable version (hosted on: https://github.com/ProjectSeptemberInc/gl-react )

Relevant example that show this issue is fixed: https://gl-react-cookbook.surge.sh/pixeleditor & others
