-<p>With SVG, you can fill (i.e., paint the interior) or stroke (i.e.,
-paint the outline) of shapes and text using one of the following:</p>
+<p>This section covers <strong>Paint Servers</strong>, a method which
+allows the <a>'fill'</a> or <a>'stroke'</a> of an object to be defined
+by a resource found elsewhere. It allows resources to be reused
+throughout a document. See the section
+<a href="painting.html">Painting: Filling and Stroking</a> for a
+general discussion of filling and stroking objects.</p>
+
+<!-- Fill and stroke are already defined in painting.html. No need to
+redefine them here." -->
+
+<p>SVG defines three types of paint servers:</p>
 
 <ul>
-  <li><a href="color.html">color</a> (using &lt;color&gt;)</li>
-
-  <li><a href="#Gradients">gradients</a> (linear or radial)</li>

 <h3 id="GradientsIntroduction">Introduction</h3>
 
-<p>Gradients consist of continuously smooth color transitions
-along a vector from one color to another, possibly
-followed by additional transitions along the same vector
-to other colors. SVG provides for two types of gradients:
-<a href="pservers.html#LinearGradients"><strong>linear
-gradients</strong></a> and <a
-href="pservers.html#RadialGradients"><strong>radial
-gradients</strong></a>.</p>
+<p>
+  Gradients consist of smooth color transitions between points on a
+  drawing surface. SVG provides for three types of gradients:
+</p>
 
-<p>Once defined, gradients are then referenced using <a>'fill'</a> or
-<a>'stroke'</a> properties on a given
-<a href="intro.html#TermGraphicsElement">graphics element</a> to indicate that
-the given element shall be filled or stroked with the referenced gradient.</p>

+  <li><a href="#RadialGradients">radial gradients</a>,</li>
+  <li><a href="#MeshGradients">mesh gradients</a>.</li>
+</ul>
 
 <p>
-The angle of the color transitions along the gradient vector is defined by the
-gradient normal. Before any transforms are applied to the gradient or its
-referencing <a href="intro.html#TermGraphicsElement">graphics element</a>, the
-gradient normal is perpendicular with the gradient vector. If a
-<a href="intro.html#TermGraphicsElement">graphics element</a> references a
-gradient, conceptually the <a href="intro.html#TermGraphicsElement">graphics
-element</a> should take a copy of the gradient vector and gradient normal and
-treat it as part of its own geometry. Any transformations applied to the
-<a href="intro.html#TermGraphicsElement">graphics element</a> geometry also
-apply to the copied gradient vector and gradient normal. Any gradient transforms
-that are specified on the reference gradient are applied before any
-<a href="intro.html#TermGraphicsElement">graphics element</a> transformations
-are applied to the gradient.
+  Once a gradient is defined, a
+  <a href="intro.html#TermGraphicsElement">graphics element</a> can be
+  filled or stroked with the gradient by setting the <a>'fill'</a>
+  or <a>'stroke'</a> properties to reference the gradient.

+<p>
+  Color transitions for linear and radial gradients are defined by a
+  series of color <a href="#GradientStops">stops</a> along a gradient
+  vector. A gradient normal defines how the colors in a vector are
+  painted to the surface. For a linear gradient, the normal
+  corresponds to lines with the same color. It is perpendicular to the
+  vector in an untransformed gradient.
+
+  When a <a href="intro.html#TermGraphicsElement">graphics element</a>
+  references a gradient, conceptually the
+  <a href="intro.html#TermGraphicsElement">graphics element</a>
+  should take a copy of the gradient vector and gradient normal and
+  treat it as part of its own geometry. Any transformations applied to
+  the
+  <a href="intro.html#TermGraphicsElement">graphics element</a>
+  geometry also apply to the copied gradient vector and gradient
+  normal. Any gradient transforms that are specified on the reference
+  gradient are applied before any
+  <a href="intro.html#TermGraphicsElement">graphics element</a>
+  transformations are applied to the gradient.

+  Color transitions for mesh gradients are defined by an array of

+  <p class="note">
+    On method of rendering a patch is to "divide and conquer."  Check
+    if the four corner colors of the patch are the same within a
+    specified tolerance. If so, paint the patch with the average color
+    using the normal path filling routine. If not, divide the patch
+    into four smaller patches and repeat the color tolerance
+    check. Repeat the process as many times as necessary.
+  </p>
+    
+  <p>
+    For a mesh, the individual patches are placed in an array. There
+    are two reasons for using an array. The first is that an array of
+    meshes is a natural result for most content creation processes
+    (start with a path and then subdivide its area into rows and
+    columns of patches).  The second is that the data can be compacted
+    by sharing sides and corners. The array structure is conceptual
+    only. The actual mesh can be distorted in any way possible. The
+    mesh gradient syntax is designed so that it is easy to simulate
+    other types of gradients such as conical gradients or triangle
+    meshes as shown in the examples below.
+  </p>
+
+  <p>
+    The structure of a mesh gradient is as follows:
+  </p>
+
+  <div class="example">
+    <pre>
+&lt;meshGradient x="100" y="100"&gt;
+  &lt;meshRow&gt;

+        Up to four stops in first patch. See details below.
+    &lt;/meshPatch&gt;
+    &lt;meshPatch&gt;
+      Any number of meshPatches in row.
+    &lt;/meshPatch&gt;
+  &lt;/meshRow&gt;
+  &lt;meshRow&gt;
+    Any number of meshRows, each with the same number of meshPatches as in the first row.
