This is set to *Mathematical Marbling* by default to keep the drops to their
initial randomly chosen places.
Made for **Gaussian-drops** and **uniform-drops**.

+## Changes in v. 1.3:
+
+## **stroke** action
+
+now becomes **stylus** action, however **stroke** still can be used.
+
+## Rotations
+
+now are consistent. From vertical clockwise
+
+## New action **serpentine-drops**
+
+**serpentine-drops** deposits a series of drops on a user-specified *grid*
+in a serpentine sequence.
+
+## New option **oversample**
+
+This option pixels the image. If taken *oversample=0* we get no-pixeled images.
+If taken *oversample=1* we get the same as with *viscosity= negative* (v1.2)
+which now is obsolete, but still works.
+The smaller the *oversample* value is taken (between 0<*oversample*<1) the more
+blocky the image gets rastered.
+
+## Transparency and Blendmodes
+
+A patch from **A. Grahn** now makes it possible to use these options the
+*normal* PSTricks way and needn't be introduced within the **actions=\{...\}**
+with raw PostScript code. Equal now for ps2pdf, xelatex and distiller.

+
+\url{http://people.csail.mit.edu/jaffer/Marbling/pst-marble-commands.pdf}
+
+\subsection*{Colors}
+
+RGB colors can be specified in three formats:
+
+\myMarble{\texttt{[ 0.906 0.8 0.608 ]}}{}
+
+Red, green, and blue color components between 0 and 1 in square
+brackets.
+
+\myMarble{\texttt{[ 231 204 155 ]}}{}
+
+Red, green, and blue color components between 0 and 255 in square
+brackets.
+
+\myMarble{\texttt{(e7cc9b)}}{}
+
+Red, green, and blue
+(\textcolor{red}{Rr}\textcolor{Mycolor2}{Gg}\textcolor{blue}{Bb})
+hexadecimal color components between \texttt{00} and \texttt{FF} (or
+\texttt{ff}) in parentheses.
+
+In the command arguments \rgbs indicates a
+bracketed sequence of colors. For example:
+
+\myMarble{\texttt{[(c28847) [231 204 155] [0.635 0.008 0.094]]}}{}
+
+
+\subsection*{Dropping Paint}
+
+\myMarble{$x$ $y$ $R_d$ \rgb}{drop}
+
+Places a drop of color \rgb and radius $R_d$ centered at location
+$x,y$.
+
+\myMarble{$x$ $y$ $R_i$ \rgbs $n$}{concentric-rings}
+
+Places $n$ rings in color sequence \rgbs centered at location $x,y$,
+each ring having thickness $R_i$.
+
+\myMarble{$x$ $y$ $\theta$ \Rs \rgbs $R_d$}{line-drops}
+
+Places drops of colors \rgbs (in sequence) of radius $R_d$ in
+a line through $x,y$ at $\theta$ degrees clockwise from vertical
+at distances \Rs from $x,y$.
+
+\myMarble{$x$ $y$ $R$ $\theta$ $S$ $\delta$ \rgbs $n$ $R_d$}{coil-drops}
+
+Places $n$ drops of colors \rgbs (in sequence) of radius
+$R_d$ in an arc or spiral centered at $x,y$ starting at radius $R$
+and $\theta$ degrees clockwise from vertical,
+moving $S$ along the arc and incrementing the arc radius
+by $\delta$ after each drop.
+
+\myMarble{$x$ $y$ $R$ $\theta$ $\epsilon$ \rgbs $n$ $R_d$}{Gaussian-drops}
+
+Places $n$ drops of colors \rgbs of radius $R_d$ randomly in a
+circular or elliptical disk centered at $x,y$ having mean radius $R$,
+$\theta$ degrees clockwise from vertical, and length-to-width ratio
+$\epsilon$. For a circular disk, 63\,\% of drops are within radius
+$R$, 87\,\% of drops are within $R\,\sqrt{2}$, and 98\,\% of drops are
+within radius $2\,R$.
+
+\myMarble{$x$ $y$ $L_x$ $L_y$ $\theta$ \rgbs $n$ $R_d$}{uniform-drops}
+
+Places $n$ drops of colors \rgbs of radius $R_d$ randomly in a $L_x$
+by $L_y$ rectangle centered at location $x,y$ and rotated by $\theta$
+degrees clockwise from vertical.
+
+\subsection*{Deformations}
+
+\myMarble{$\theta$ \Rs $V$ $S$ $D$}{rake}
+
+Pulls tines of diameter $D$ at $\theta$ degrees from the y-axis
+through the virtual tank at velocity $V$, moving fluid on the tine
+path a distance $S$. The tine paths are spaced \Rs from the tank
+center at their nearest points.
+
+\myMarble{$x_b$ $y_b$ $x_e$ $y_e$ $V$ $D$}{stylus}
+
+Pulls a single tine of diameter $D$ from $x_b,y_b$ to $x_e,y_e$ at
+velocity $V$. Legacy \texttt{stroke} also works.
+
+\myMarble{$x$ $y$ \Rs $\omega$ $\theta$ $D$}{stir}
+
+Pulls tines of diameter $D$ in circular tracks of radii \Rs (negative
+$R$ is counterclockwise) around location $x,y$ at angular velocity
+$\omega$. The maximum angle through which fluid is moved is $\theta$
+degrees.
+
+\myMarble{$x$ $y$ $\Gamma$ $t$}{vortex}
+
+Rotates fluid clockwise around location $x,y$ as would result from an
+impulse of circulation $\Gamma$ after time $t$. At small $t$ the
+rotational shear is concentrated close to the center. As time passes
+the shear propagates outward.
+
+\myMarble{$\theta$ $\lambda$ $\Omega$ $S$}{wiggle}
+
+Applies sinsusoidal wiggle with period $\lambda$ and maximum
+displacement $S$ to whole tank. With $\theta=0$, a point at $x,y$ is
+moved to $x+S\,\sin(360\,y/\lambda+\Omega),y$.
+
+\myMarble{$\theta$ $R$}{shift}
+
+Shifts tank by $R$ at $\theta$ degrees clockwise from vertical.
+
+\myMarble{\texttt{[} $n$ $S$ $\Omega$}{tines} \texttt{]}
+
+The tines command and its arguments are replaced by a sequence of $n$
+numbers. The difference between adjacent numbers is $S$ and the center
+number is $\Omega$ when $n$ is odd and $S/2-\Omega$ when $n$ is even.

+Marbling originated in Asia as a decorative art more than 800 years ago and spread to Europe in the 1500s where it was used for end-papers and book covers.
The mathematical fascination with paint marbling is that while rakings across the tank stretch and deform the paint boundaries, they do not break or change the topology of the surface. With mechanical guides, a raking can be undone by reversing the motion of the rake to its original position. Raking is thus a physical manifestation of a homeomorphism, a continuous function between topological spaces (in this case between a topological space and itself) that has a continuous inverse function.

The documentation illustrates the parameters that are now used:
Center coordinates in mm, circulation in $\mathrm{mm^2/s}$ and time in s.
-The primitive \texttt{line} has now become \texttt{rake} and allows to represent the obtained image when the artist equips himself with a comb (rake) comprising a certain number of identical teeth of a given diameter. He places the comb perpendicularly to a direction fixed by the angle made with the $Oy$-axis (the angle is positive clockwise) and moves it with a speed of (\texttt{V}) along the indicated direction or contrary to it, depending on the sign of the parameter \texttt{tU}. The positions of the teeth are fixed by the distances (in mm) indicated within the list [between the brackets]---the comb/rake can also comprise only one tooth.

Initially there are drops of colors that the artist spreads with a brush on the surface (a bit of a hazard, even if they are located in a given region) and whose size depends on the brush. He performs the operation several times with other colors and also brushes of different sizes. These single drops, circular in shape, are placed with the following command
\begin{verbatim}
- cx cy r [rgb]
0 0 100 [0 0 1] drop
\end{verbatim}
Note, that the coordinates (\texttt{cx, cy}) of the center of the drop and its radius \texttt{r} are in points, the colors need to be setup in the rgb-color-system: (values between 0 and 1). Details are given in the following sections. So this is the first phase: arrange the drops on the surface in several stages with different radii and colors. To facilitate the experimentation of different types of actions, Aubrey Jaffer imagined an initial background obtained by dropping (one after the other) drops of different colors (we can also differentiate their radii) at the same point, they all have the same center, we then obtain an initial background consisting of concentric rings, named ``concentric-rings''.
-Aubrey Jaffer coded all the possible simulations with the expected deformations (rake, stroke, stir, wiggle, vortex) in pure PostScript and his new code, perfectly structured, and whose use is very simple, would be enough to itself, if it weren't necessary for each test, to add lines, delete others, save them within the original PostScript file \ldots

Many thanks to D. P. Story who coded some additions to the \texttt{pst-marble.pro} file so it might be used for Adobe Distiller users.
The file size for the documentation could so be reduced tremendously.
