Feature Request: TextureImporter.GetWidthAndHeight

public static bool GetImageSize(Texture2D asset, out int width, out int height) {
    if (asset != null) {
        string assetPath = AssetDatabase.GetAssetPath(asset);
        TextureImporter importer = AssetImporter.GetAtPath(assetPath) as TextureImporter;

        if (importer != null) {
            object[] args = new object[2] { 0, 0 };
            MethodInfo mi = typeof(TextureImporter).GetMethod("GetWidthAndHeight", BindingFlags.NonPublic | BindingFlags.Instance);
            mi.Invoke(importer, args);

            width = (int)args[0];
            height = (int)args[1];

            return true;
        }
    }

    height = width = 0;
    return false;
