three.js at 9b4a2ac enables colour management by default with a Linear-sRGB working space and converts with the piecewise sRGB functions (thresholds 0.04045 and 0.0031308, slope 12.92, exponents 2.4 and 0.41666, the latter a truncation of 1/2.4). Texture annotation rules, outputColorSpace and the OutputPass double-conversion warning are from manual pages not re-read.
