Don't make me upload my web-browser-in-a-GLSL-shader snippet
Web browser in a shader also sounds extremely inefficient, for obvious fundamental reasons.
The GLSL I originally posted is from the "cursed mode" of my side project, and I use it to produce a data URI of every frame, 15 times per second, as a twisted homage to old hardware. (No, I didn't use AI :P )

That said, is `pow(vec4(2),-vec4(2,4,6,0))` really so bad? I figured it'd be replaced with `vec4(0.25, 0.0625, 0.015625, 1.0)`.
