Used for shaders that need noise textures.
Still WIP. needs the nodes to set their appropriate values when setting a noise texture. Which means I'll probably have to re-write the whole thing, yay :D
Simply add `uniform float PXO_time;` in the shader's uniforms, and replace all instances of `TIME` with `PXO_time`. This will make the shader animate per frame.
* experimental support for texture changes
* fix some typos
* formatting + some improvements
* Some final touches, i think it's ready now
* moved a function to the shaderloader
* formatting
* add a void
