/**
 * Color-space bridge for glTF material factors.
 *
 * glTF 2.0 defines `pbrMetallicRoughness.baseColorFactor` in **linear** space
 * (spec §3.9.2), while a melonJS `tint` is an 8-bit **sRGB** value — the same
 * space as a CSS color or a texel out of a PNG. Handing the linear number
 * straight to `tint.setColor(f * 255)` therefore displays every untextured
 * glTF material far too light and desaturated: a linear `0.29` shows up as
 * sRGB `0.58`, so an authored mid-green renders as pale mint.
 *
 * The encode below is the standard sRGB transfer function.
 * @module level/gltf/srgb
