Postprocessing compose needs srgb=false

[vorg]

For legacy and compatibility reasons with SMAA current combine texture seems to be in srgb8 encoding causing banding for HDR colors.

In nodes we use the following fix

 const combinePass = renderPipelineSystem.postProcessingEffects?.find(
  ({ name }) => name === "combine",
);
if (combinePass) {
  combinePass.srgb = false;
}

Needs investigation on source of banding and need for SRGB8_ALPHA8 textures vs RGBA16F

This does not work if you have MSAA or SMAA enabled. You will get SRGB8 texture regardless.
