基本上 HIG 说黑色 HUD UI 被称为透明面板。
它的作用与标准面板相同，即提供一些与当前文档相关的控件的辅助窗口。
它的外观尽可能离散，特别是在高度视觉化的应用中。
Basically HIG say that black HUD UI is named a transparent panel.
Its role is the same as a standard panel, i.e., an auxiliary window that offers some controls related to the current document.
Its look is as discrete as possible, in particular in highly visual applications.
