tufte-book 中新增了浮动环境，可为全宽图形提供替代标题位置

Question

这是我用来使某事奏效的方法。不是最巧妙的……

我将 @tufte@float 环境定义和 \@tufte@float@fullwidth 命令定义复制到我的前言中，分别将它们重命名为 @TC@float 和 \@TC@float@fullwidth。

我改变了我的 plate* 环境定义以使用 @TC@float 而不是标准的 tufte-class figure* 环境。

这使我可以改变标题文本框的宽度（改变行 \begin{minipage}[\floatalignment]{2\marginparwidth}\hbox{} 使其成为正常宽度的两倍）和位置，方法是强制 \@TC@float@fullwidth 仅使用我想要的选项（有效地注释掉不需要的选项）。

由于我的 \textwidth = 2\marginparwidth，并且 \@TC@float@fullwidth 中的选项允许位置位于左下方，因此我可以在图形下方和正文通常填充的相同空间中显示一个长标题。

解决方案：左下角标题和正文的宽度
