This module performs an Euclidean transformation (zoom, rotation and
translation)
\index{zoom!of a curve}
\index{rotation!of a curve}
\index{translation!of a curve} 
on a set of Fcurves. The needed
parameters are the zoom factor $zoom$, the rotation angle
$angle$, and the translation vector $(x,y)$. To
each point of the original Fcurves the transformation
$$\left( \begin{array}{c} X \\ Y \end{array} \right) \quad
\mapsto \quad zoom \cdot 
\left( \begin{array}{cc}  \cos(\theta) & - \sin(\theta) \\
 \sin(\theta) & \;\;\;\cos(\theta) \\ \end{array} \right) \;
\left( \begin{array}{c} X \\ Y \end{array} \right) \;+\;
\left( \begin{array}{c} x \\ y  \end{array} \right)$$
is applied,
where $\displaystyle \theta = angle \cdot \frac{\pi}{180}$.
