+The built-in determination of the bounding box in TikZ is not entirely accurate.
+This is because, for Bezier curves, it is the smallest box that contains all
+control points, which is in general larger than the box that just contains the
+curve. This library determines the exact bounding box of the curve.
+
+In order to load this library in a LaTeX document, you need to add 
+
+\usetikzlibrary{bbox}
+
+to the preamble after loading the tikz package. While this library might
+possibly work with TeX or ConTeXt, this has never been tested. This library
+loads and uses the fpu library.

+\section{Bounding Boxes for B\'ezier Curves}
+
+
+\begin{pgflibrary}{bbox}
+    This library provides methods to determine tight bounding boxes for
+    B\'ezier curves. This library loads and uses the
+	|fpu| library. While this library might
+	possibly work with |TeX| or |ConTeXt|, this has never been tested.
+\end{pgflibrary}
+
+\subsection{Bounding box without the library}
+
+\tikzname\ determines the bounding box of (cubic) Bezier curves by establishing the
+smallest rectangle that contains the end point and the two control points of the
+curve.
+
+\begin{codeexample}[width=5cm]
+\begin{tikzpicture}[%
+	bullet/.style={circle,fill,
+		inner sep=1pt}]
+ \draw (0,0) .. controls (-1,1) 
+ 	and (1,2) .. (2,0);
+ \draw (current bounding box.south west) 
+ 	rectangle 
+  (current bounding box.north east);
+ \draw[red,dashed] 
+ 	(0,0) -- (-1,1) 
+	node[bullet,label=above:{$(x_a,y_a)$}]{}
+    (2,0) -- (1,2) 
+	node[bullet,label=above:{$(x_b,y_b)$}]{};
+ \path (0,0) 
+ 	node[bullet,label=below:{$(x_0,y_0)$}]{}
+ 	(2,0) 
+	node[bullet,label=below:{$(x_1,y_1)$}]{};
+\end{tikzpicture}
+\end{codeexample}
+
+As one can see from this illustration, this may lead to drastic overestimates of
+the bounding box.
+
+\subsection{Computing the bounding box}
+
+Establishing the precise bounding box has been discussed in various places, the
+following discussion uses in part the results from
+\url{https://pomax.github.io/bezierinfo/}. What is a cubic B\'ezier curve? A
+cubic B\'ezier curve running from $(x_0,y_0)$ to $(x_1,y_1)$ with control points
+$(x_a,y_a)$ and $(x_b,y_b)$ can be parametrized by
+\begin{equation}
+ \gamma(t)~=~
+ \begin{pmatrix} x(t)\\ y(t) \end{pmatrix}~=~
+ \begin{pmatrix}t^3 x_{1}+3 t^2 (1-t) x_{b}+(1-t)^3
+   x_{0}+3 t (1-t)^2 x_{a}\\
+   t^3 y_{1}+3
+   t^2 (1-t) y_{b}+(1-t)^3 y_{0}+3 t (1-t)^2
+   y_{a}\end{pmatrix}\;,\label{eq:gammaBezier}
+\end{equation}
+where $t$ runs from $0$ to $1$ (and $\gamma(0)=(x_0,y_0)$ and
+$\gamma(1)=(x_1,y_1)$). Surely, the bounding box has to contain
+$(x_0,y_0)$ and $(x_1,y_1)$. If the functions $x(t)$ and $y(t)$ have extrema in
+the interval $[0,1]$, then the bounding box will in general be larger than that.
+In order to determine the extrema of the curve, all
+we need to find the extrema of the functions $x(t)$ and $y(t)$ for $0\le t\le
+1$. That is, we need to find the solutions of the quadratic equations
+\begin{equation}
+ \frac{\mathrm{d}x}{\mathrm{d}t}(t)~=~0\quad\text{and}\quad
+ \frac{\mathrm{d}y}{\mathrm{d}t}(t)~=~0\;.
+\end{equation}
+% (*parametrization of x:*)
+% myx = x0 (1 - t)^3 + 3 xa (1 - t)^2 t + 3 xb (1 - t) t^2 +  x1 t^3 
+% (*d1\ne0 condition for t1 and t2 to exist*)
+% === (*case d1\ne0*) == 
+% d1 =  x0 - x1 - 3 xa + 3 xb
+% (*square root, d2=0 \[Rule] only one solution,d2<0 \[Rule] no solution*)
+% d2 =  x0*x1 - x1*xa + xa*xa - x0*xb - xa xb +  xb*xb 
+% (*first t*)
+% t1 = (x0 - 2*xa + xb - sqrt(d2))/(x0 - x1 - 3*xa + 3*xb)
+%    = (x0 - 2*xa + xb - sqrt(d2))/d1
+% (*second t*)
+% t2 = (x0 - 2*xa + xb + sqrt(d2))/(x0 - x1 - 3*xa + 3*xb)
+%    = (x0 - 2*xa + xb + sqrt(d2))/d1
+% === (*case d1=0*) == 
+% (*2nd condition for extra condition: d3\ne0*)
+% d3 = x1 + xa - 2 xb
+% (*third t*)
+% t3 = (x1 + 2*xa -  3*xb)/(2*d3)% d3 = x1 + 3 xa - 3 xb - x0
+Let's discuss $x$ first. If the discriminant
+\begin{equation}
+ d~:=~x_0\,x_1 - x_1\,x_a + x_a\,x_a - x_0\,x_b - x_a x_b +  x_b\,x_b
+\end{equation}
+is greater than 0, there are two solutions
+\begin{equation}
+ t_\pm~=~\frac{x_{0}-2x_{a}+x_{b}\pm\sqrt{d}}{%
+ 	x_{0}-x_{1}-3(x_{a}- x_{b})} \;.
+\end{equation}  
+If the denominator $x_{0}-x_{1}-3(x_{a}- x_{b})$  vanishes, one may use the
+l'Hospital rule to determine the solutions.
+In this case, we need to make sure that the bounding box contains, say
+$(x(t_-),y_0)$ and $(x(t_+),y_0)$. If $d\le0$, the bounding box does not need to
+be increased in the $x$ direction. On the other hand, if there are solutions,
+one needs include the points $\bigl(x(t_\pm),y_0\bigr)$ with $x(t)$ from
+\eqref{eq:gammaBezier} in the bounding box. 
+
+The analogous statements apply to $y(t)$. 
+
+\subsection{Using the library}
+
+\begin{key}{/pgf/bezier bounding box=\meta{boolean} (default true)}
+    Turn the tight bounding box algorithm on and off. The initial value is
+	|false|.
+
+	\emph{Caveat:} As can be seen from the derivations, the necessary
+	computations involve the squaring of lengths and taking ratios of lengths,
+	which can easily lead to |dimension too large| errors. The library uses
+	|fpu| to account for that, but errors may still occur.
+\end{key}
+
+
+\begin{codeexample}[width=5cm]
+\begin{tikzpicture}[bezier bounding box,%
+	bullet/.style={circle,fill,
+		inner sep=1pt}]
+ \draw (0,0) .. controls (-1,1) 
+ 	and (1,2) .. (2,0);
+ \draw (current bounding box.south west) 
+ 	rectangle 
+  (current bounding box.north east);
+ \draw[red,dashed] 
+ 	(0,0) -- (-1,1) 
+	node[bullet,label=above:{$(x_a,y_a)$}]{}
+    (2,0) -- (1,2) 
+	node[bullet,label=above:{$(x_b,y_b)$}]{};
+ \path (0,0) 
+ 	node[bullet,label=below:{$(x_0,y_0)$}]{}
+ 	(2,0) 
+	node[bullet,label=below:{$(x_1,y_1)$}]{};
+\end{tikzpicture}
+\end{codeexample}
+
+A few comments are in order. 
+\begin{enumerate}
+\item For paths with arrow heads one may need to load the \texttt{bending}
+ library. This is because otherwise the quick arrow head distorts the path, and
+ this happens after the bounding box has been computed. Even worse, arrow heads
+ could get deformed.
+\item If you shorten a path by some negative length, the bounding box will not
+ be accurate either. However, this has nothing to do with curves, it also
+ applies to straight lines. So this is not specific to the |bbox| library but
+ something that one may want to keep in mind.
+\item Let us also note that the computations can lead to |Dimension too large|
+ errors. These errors do not come directly from the computations done by the
+ library, which uses |fpu| for its computations, but from the aftermath. Many of
+ these problems can be avoided by using the |fpu| library also for computing
+ reciprocals, which can be achieved using the key 
+ |/pgf/fpu/install only={reciprocal}|. This allows one to fix many 
+ |Dimension too large| errors in  other libraries, which are not related to the
+ present one, and also fixes inaccuracies of (inverse) transformations when the
+ scale factors are not integer.
+\end{enumerate}
+
+\subsection{Reporting a bug}
+
+This library is maintained at the GitHub repository
+\href{https://github.com/marmotghost/tikz-bbox}{tikz-bbox}, where issues can get
+reported. The author is also active on the noncommercial \TeX\ Q\,\&\,A site
+\href{https://topanswers.xyz/tex}{topanswers.xyz/tex}, where requests that are not
+issues in the strict sense can be discussed.
