/**
 * Define additional watermark configurations in the client-side.
 *
 * In most cases, the majority of options should be defined in Node,
 * but there are some special situations. For example,
 * it may be necessary to control different watermark opacities, font colors,
 * etc., in dark/light mode, or to pass in callbacks such as `onSuccess`, `extraDrawFunc`, and so on.
 *
 * 在客户端中定义额外的水印配置。
 *
 * 通常来说，大部分选项应该在 Node 中定义，但存在一些特殊情况。
 * 比如需要在 深色/浅色 模式下控制不同的 水印 透明度、字体颜色等，
 * 或者需要传入如 `onSuccess`、`extraDrawFunc` 等回调函数。
 *
 * @example
 * ```ts
 * import { computed } from 'vue'
 *
 * const isDark = useDarkMode()
 *
 * const watermarkConfig = computed(() => ({
 *   fontColor: isDark.value ? '#fff' : '#000',
 *   onSuccess: () => {
 *     console.log('success')
 *   },
 * }))
 *
 * defineWatermarkConfig(watermarkConfig)
 * ```
 *
 * @param userConfig Watermark options
 *
