Based on 'Trypophobia' by warlock and porting by JiPi.
After the conversion, black glitches first appeared here. It took me some time to find the job at the Raymarcher. Obviously, WebGL is much more error-friendly with the code here. But now I was only able to create one bump map. It felt like it took an eternity until I realized that the iChannel0 is obviously "lost" in the depths of the parameter transfers. The variant with global textures works perfectly. In a quiet minute I'll try the OpenCL variant again.
