背景：我正在设计自己的
beamer模板，并且我已经阅读如何从头开始设计自定义 Beamer 主题和如何创建 Beamer 模板我还读到beamer 如何构建框架。
我注意到，在上述问题中发现的每个示例中，框架都是使用多个环境构建的（每个环境内都创建beamercolorbox一个）。 我知道 LaTeX 可以使用框，但是...tikzpicture
我想在创建 TikZ 图片时定义我的模板，即使用相对定位的节点，并用诸如\insertframenumber、\inserttitle、 之类的宏填充\insertcontent。
我已经成功实现了我的愿望titleframe（见下文）。
但是，我无法在常规幻灯片上实现相同的效果。事实上，当我无法叠加通过 定义的 TikZ 图片\frametitle和\framesubtitle幻灯片内容时，也无法subtitle相对于 进行定位title。另外，我没有使用方形文本区域 - 如下例所示（手动完成）：
请注意，我不太可能使用块（例如definition，theorem等）。段落的梯形形式将使用以下方式定义shapepar包定义（参见示例示例）在 TikZ 中将文本调整到形状和创建自定义梯形文本框）。
笔记：我并不是要求你为我编写这个模板，而是如何使用 TikZ 节点定义整个框架的布局？（即定位每个组件，例如frametitle，slidenumber等） - 包括其内容。

There is no largest prime number.
\begin{enumerate}
\item<1-| alert@1> Suppose $p$ were the largest prime number.
\item<2-> Let $q$ be the product of the first $p$ numbers.
\item<3-> Then $q+1$ is not divisible by any of them.
\item<1-> But $q + 1$ is greater than $1$, thus divisible by some prime
number not in the first $p$ numbers.

[以下内容不包含 parshape 内容（我想你可以从你提供的链接中复制代码）]
为什么要花功夫用 tikz 来定位 frametitle 等？我认为您的设计可以用经典的 beamer 工具来完成：
