crypto_aux_image_with takes CryptoAux::{ColorsAndMatte, MatteOnly}, and
CryptoAux::for_display holds the rule for which displays read the ID
colours. A new GPU test checks every display x Matte Only against the CPU,
so the GPU fails the test if the shader starts reading RGB in a mode that
skips it (checked by mutation: forcing MatteOnly fails display 0).
3D Channel Extract, Cryptomatte, Depth Matte, Depth of Field, EXtractoR, Fog 3D,
ID Matte and IDentifier run on the GPU (fx_depth.rs / fx_depth.wgsl): aux planes
upload as a texture and are resampled onto the buffer grid with the CPU's index
arithmetic; tests compare against the CPU at 1x / 2x aux resolution, padded
buffers, half resolution and 8 / 32 bpc composites.
