style (Visual Basic hexadecimal) is not supported - if a parser finds any colour in \&HBBGGRR\& format,
it \must\ issue an error.
In the tag specification in this document, optional parameters are denoted by being enclosed by square
brackets (``[]''), and may be ommitted. For example, \emph{\textbackslash baseline(curve1[,curve2])}
means that the second parameter is entirely optional. It's also possible that the entire parameter set
is enclosed in square brackets, e.g. \emph{\textbackslash vc[(c1,c2,c3,c4)]}.
Any tag might have its parameter enclosed inside parenthesis (``()''), but some tags require it. In
particular, any tag that has more than on parameter, or whose parameter is text requires parenthesis.
The parser \must\ issue a warning and disregard the tag if it ommitted mandatory parenthesis.

\item Normalize the (x,y) coordinates to a (u,v) system, so that $P_0$ = (0,0) and $P_2$ = (1,1).
This can be done by dividing x by the block's baseline length (bl) and y by the block height (h).
The affine 3D transformation matrix for this operation is:\\
\[ \left[\begin{array}{ c c c c }
\begin{center}
$\begin{bmatrix}
\frac{1}{bl} & 0 & 0 & -\frac{P_{0x}}{bl} \\
0 & \frac{1}{h} & 0 & -\frac{P_{0y}}{h} \\
0 & 0 & 1 & 0 \\
0 & 0 & 0 & 1
\end{array} \right]\]\\
\end{bmatrix}$
\end{center}
%\vspace{10pt}
That is, $u = \frac{P_x - P_{0x}}{bl}; v = \frac{P_y - P_{0y}}{h}$.
\item Apply the following formula: $P = P_0 + (P_1-P_0) u + (P_3-P_0) v + (P_0+P_2-P_1-P_3) u v$.\\
This can be interpreted as simple vector operations, that is, apply that once using the x coordinates
