[BUG] Radial Gradient only rendering the last color

[binber18]

Description
When rendering radial gradients it seems that the library only renders the last color of that color stack.

Code

using System.Text;
using SkiaSharp;

var svgText = """
            <?xml version="1.0" encoding="UTF-8" standalone="no"?>

Console.WriteLine("Done!");

Expected Behavior

A PNG that with the same Colors as the SVG

Actual Behavior

A PNG that is just blue

The SkiaSharp.Svg is no longer support or maintained. However, there is a far better library with almost full SVG support: https://github.com/wieslawsoltes/Svg.Skia

Closing this issue for now as SkiaSharp.Svg will not receive any updates and the code has been removed from the main branch.
