Is Transverse Chromatic Aberration possible?

This isn't an issue with GPUImage2, but I'd like to know how possible it would be to create an effect like this with it: https://github.com/FlexMonkey/Filterpedia/blob/master/Filterpedia/customFilters/TransverseChromaticAberration.swift

You should be able to translate the CIKernel there into a fragment shader fairly easily in order to reproduce the same effect. You just need to extract the transverseChromaticAberrationKernel and convert the relevant inputs and outputs into GLSL, following the template of one of the existing filters in the framework.

Awesome thank you! I have no experience working with fragment shaders or GLSL but I'll give it a shot!
