VR Blur, Chromatic Aberrations, Color Gradients, Converter (all projections and
cube layouts), De-Noise, Digital Glitch, Fractal Noise, Glow, Plane to Sphere,
Rotate Sphere, Sharpen and Sphere to Plane run on the GPU (fx_vr.rs /
fx_vr.wgsl) with the CPU's equirectangular maths: seam-wrapping, pole-continuing
sampling and latitude-widened box blurs, per eye for stereo layouts.
