Subject: [PATCH] Very simple fix for where linear gradient is used as a border
 between, say, a slider and its background. Interpolating as SRGB involves a
 conversion in rust and conversion back in shader using different maths
 leading to slightly off colors, interpolating as linear is clean and produces
 exact results
