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

Objective

• Noticed that a slider with same BG color as the surrounding area still appeared slightly different, fixed by tracing through where the colors were coming from.

Solution

• Changed interpolation to linear, which basically means there is no two way conversion

Showcase

Before (annotation text added afterwards, difference is probably only visible with an eyedropper tool)

Yep, nice practical solution.

We should look into the mismatch in the colour conversion code though and see if its accuracy can be improved. I'll add an issue.
