It renders a Cartesian grid in the active layer, on top
of the existing contents. The width, spacing, offsets, and
colors of the grid lines can all be set by the user. By
default, the lines are colored dark blue. (Note: this
plugin was used to create demonstration images for many of the
other plugins.)

There are separate options for controlling the horizontal grid
lines, vertical grid lines, and intersections. By default, the
horizontal and vertical settings are locked together, so that
all changes are applied symmetrically. If you want to change
just one of them, click on the "chain" symbol below it to unlock
them. The results of changing the "intersection" parameters are
rather complex.
</p>
<div class="variablelist">

<dd>
<p>
Sets the widths of the horizontal or vertical grid
lines, or of the symbols drawn at their intersections.
</p>
</dd>
<dt>
<span class="term">Spacing</span>
</dt>
<dd>
<p>
Sets the distance between grid lines. For intersections,
sets the distance from the intersection point for the
starting points of the line segments that are drawn.
</p>
</dd>
<dt>
<span class="term">Offset</span>
</dt>
<dd>
<p>
Sets the offset for grid lines with respect to the upper
left corner. For intersections,
sets the distance from the intersection point for the
ending points of the line segments that are drawn.
</p>
</dd>

<span class="term">Color Selectors</span>
