 ## Changes in v. 1.3a: 
 
 ## Bug fixes
+
+---
+
+## Changes in v. 1.4:
+
+## The command **\\psMarble** 
+
+is now available in two forms:
+
+**\psMarble\[parameter-assignment,...,parameter-assignment\](width,height)**
+
+**\psMarble\[parameter-assignment,...,parameter-assignment\](x−,y−)(x+,y+)** 
+
+## New option **overscan**
+
+When the overscan value is greater than 1, proportionally more image 
+(outside of the specified area) is shown, and the specified area is outlined 
+with a dashed rectangular border.
+
+## New option **spractions** with new post-marble actions
+
+Specifies the sequence of spray commands to perform. 
+Spray commands are performed after marbling.
+
+## **Gaussian-spray**
+
+**xc yc r ang eccentricity \[ rgb \] n Rd Gaussian-spray**
+
+Places **n** drops of colors **\[rgb\]** randomly in a circular 
+or elliptical disk centered at **xc, yc** having mean radius **Rd**, 
+**ang** degrees clockwise from vertical, and length-to-width ratio 
+**eccentricity**.

+
+Places **n** drops of colors **\[rgb\]** randomly in a **xsid** by **ysid**

+
+Specifies a color sequence accessible in paint-dropping commands as
+\texttt{colors}.
+
+\myparam{drawcontours}{false}
+
+When \texttt{drawcontours=true} paint contours are drawn with lines;
+when \texttt{drawcontours=false} contours are filled;
+
+\myparam{oversample}{0}
+
+When \texttt{oversample=0} a resolution-independent image is produced
+using contour-rendering.  When the number of drops gets too large
+($>150$) triangular artifacts start to appear.  Changing to
+\texttt{oversample=1} employs raster-rendering to more quickly compute
+each image pixel individually.  When \texttt{oversample=2} the
+rendering takes four times as long, but each pixel is the averaged
+over its four quarters, producing an image nearly as good as
+\texttt{oversample=0}.  When \texttt{oversample} is between 0 and
+1, the rendering is on a coarser grid than \texttt{oversample=1},
+speeding image production.
+
+\myparam{overscan}{1}
+
+When the \texttt{overscan} value is greater than 1, proportionally
+more image (outside of the specified area) is shown, and the specified
+area is outlined with a dashed rectangular border.  This is a utility
+for developing marblings, new for version 1.4.
+
+\myparamb{seed}{Mathematical Marbling}
+
+Specifies the random seed used for \texttt{Gaussian-drops} and
+\texttt{uniform-drops} commands.  Changing the \texttt{seed} value
+changes the positions of all drops from the \texttt{Gaussian-drops}
+and \texttt{uniform-drops} commands.

+\myparam{viscosity}{1000}
 
+Specifies the overall kinetic viscosity of the virtual tank fluid.
+Its units are $\rm{mm^2/s}$; the default value of 1000, which is 1000
+times more viscous than water, is a typical value for marbling.
+Increasing \texttt{viscosity} reduces the fluid movement far from the
+tines.
+
+\myparamb{actions}{0 0 36 colors 35 concentric-rings}
+
+Specifies the sequence of marbling commands to perform.  The default
+is a single command dropping 35 colors in the \texttt{colors}
+sequence.  The available commands are listed below.

+
+Specifies the sequence of spray commands to perform.  Spray commands

+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.

+\section{Spray actions}

+Spray actions are intended for drops small enough that they don't noticeably move paint boundaries. The radii of spray droplets are the cube roots of log-normal distributed values with mean \texttt{Rd}.
+
+Spray commands are performed after marbling!

+
+\subsection{\texttt{Gaussian-spray}}

+\begin{verbatim}
+xc yc r ang eccentricity [ rgb ] n Rd Gaussian-spray
+\end{verbatim}
+Places \texttt{n} drops of colors \texttt{[rgb]} randomly in a circular or elliptical disk centered at \texttt{xc, yc} having mean radius \texttt{Rd}, \texttt{ang} degrees clockwise from vertical, and length-to-width ratio \texttt{eccentricity}. 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 $2r$.
