Allows SVG gradients to interpolate in a linear-light sRGB color space. Currently all SVG gradients interpolate in a gamma-encoded sRGB color space.
The 'color-interpolation' property - and the 'linearRGB' value - has been in the SVG specification for a long time, but not been supported in the context of gradients. With the recent advancements in color handling it is now very simple to support and provides some level of improved color support for SVG gradients ('linearGradient' and 'radialGradient' element).
