Brandon Thomas 069852286b Render: two-colour gradients ramp like PowerPoint's PowerPoint blends a gradient of exactly two stops at 0% and 100% in linear light, with the second colour's share following an S-shaped curve (black to white is 105/186/238 at a quarter/half/three quarters, not 64/128/191). Gradients with more stops, or a stop moved off an end, stay linear in sRGB. Measured with PowerPoint's slide export on shapes and backgrounds, in both directions. The two-colour case is expanded into sixteen pieces per segment so vello's sRGB interpolation draws the same ramp.

PowerPoint blends a gradient of exactly two stops at 0% and 100% in linear
light, with the second colour's share following an S-shaped curve (black to
white is 105/186/238 at a quarter/half/three quarters, not 64/128/191).
Gradients with more stops, or a stop moved off an end, stay linear in sRGB.
Measured with PowerPoint's slide export on shapes and backgrounds, in both
directions. The two-colour case is expanded into sixteen pieces per
segment so vello's sRGB interpolation draws the same ramp.
