+- added partial implementation of PostScript operator 'shfill' to create color
+  gradient fills (supported shading types: free-form triangular, lattice-form
+  triangular, Coons, and tensor-product patch meshes)
+- added options --grad-segments, --grad-overlap, and --grad-simplify to control
+  the approximation of color gradients
+- added option --no-merge to create separate text elements for each character
+  (patch by Khaled Hosny)
+- added a simple progress counter to the EPS to SVG converter
+- added opt2cpp.py as a free replacement for my non-free opt2cpp.xsl script
+  (thanks to Khaled Hosny for the implementation and for providing it for free)
+- added lookup of Ghostscript library in the Windows registry
+- fixed validity check of DVI files
+- fixed interaction of color specials and PostScript color operators
+- several code refactorings and improvements
+
 dvisvgm-1.8.1 (2014-08-29)
 - unreferenced clipPath elements are now removed from the SVG files
 - fixed side-effectes caused by unexpected bop/eop operators in

Unfortunately, this alignment can lead to visible gaps between the segments because the background influences the color at the boundary of the segments if the SVG renderer uses anti\-aliasing to create smooth contours\&.

Since the latter are drawn on top of the overlapping parts, the visible size of all segments keeps unchanged\&. Just the former gaps disappear as the background is now completely covered by the correct colors\&.

Since SVG 1\&.1 only supports a small subset of the shading algorithms available in PostScript, dvisvgm approximates some of them by subdividing the area to be filled into smaller, monochromatic segments\&. Each of these segments gets the average color of the region it covers\&.

As a drawback, more segments imply bigger SVG files because every segment is represented by a separate path element\&.

+number of segments leads to smaller monochromatic areas and therefore results in a better approximation
+of the actual color gradient. As a drawback, more segments imply bigger SVG files because every
+segment is represented by a separate path element.
++
+Currently, dvisvgm supports free- and lattice-form triangular patch meshes as well as Coons and
+tensor-product patch meshes. They are approximated by subdividing the area of each patch into a
+__n__&#215;__n__ grid of smaller segments. The maximal number of segments per column and row can be
+changed with option *--grad-segments*.
+
+
+*--grad-simplify*='delta'::
+If the size of the segments created to approximate gradient color fills falls below the given delta
+value, dvisvgm reduces their level of detail. For example, Bézier curves are replaced by straight
+lines, and triangular segments are combined to tetragons. For a small delta these simplifications
+are usually not noticeable but reduce the size of the generated SVG files.

 The famous DVI driver dvips introduced its own set of specials in order to embed PostScript code into DVI files,
