PSDNET-1450. 实现渐变映射图层的支持

string sourceFile = Path.Combine(baseFolder, "gradient_map_src.psd");
string outputFile = Path.Combine(outputFolder, "gradient_map_src_output.psd");

using (PsdImage im = (PsdImage)Image.Load(sourceFile))
{
    // 添加渐变映射调整图层。
    GradientMapLayer layer = im.AddGradientMapAdjustmentLayer();
    layer.GradientSettings.Reverse = true;

    im.Save(outputFile);
}

// 检查保存的更改
using (PsdImage im = (PsdImage)Image.Load(outputFile))
{
    GradientMapLayer gradientMapLayer = im.Layers[1] as GradientMapLayer;

    AssertAreEqual(false, gradientSettings.AlignWithLayer);
    AssertAreEqual(false, gradientSettings.Dither);

PSDNET-1670. 【AI 格式】添加对 AI 格式的 XPacket 元数据的支持

    }
