<h2>How to add a new tool</h2>
<p>
The JavaScript class GeomToolFromFile allows one to insert objects
defined in SVG files. Example:
</p>
<pre>
let p = new GeomPaper("canvas_container1", 1000, 600);
let o3 = new GeomToolFromFile(
p, "equerre01",
"/usr/share/javascript/schoolkit/equerre01.svg",
new DOMPoint(300,150),
1);
</pre>
<p>
The SVG file must contain
<ul>
<li>A <g> group element with an attribute id="layer1";
this group must then contain:</li>
<li>A <circle> circle element whose center, defined by the
attributes cx and cy will be the center of rotation for the
geometric tool; this circle must have the attribute id="centre";
</li>
<li>A random graphic element, with the attribute
id="rotation_handle"; it should not overlap the central point,
because it will be used to control the rotation upon dragging;
</li>
<li>A random graphic element, with the attribute
id="translation_handle" which will be used to control the
translation upon dragging;
</li>
<li>
And any number of other graphic elements appended to the
main group.
</li>
</ul>
</p>
<h2>Demo</h2>
<div class="svg_container" id="canvas_container1"></div>
<script>
let p = new GeomPaper("canvas_container1", 1000, 600);
p.quadrillage();
let o1 = new GeomToolFromFile(p, "rapporteur01", "/javascript/schoolkit/rapporteur01.svg",
new DOMPoint(500,300), 1);
// let o2 = new DoubleDecimetre(p, 105, 100, "dd01")
// p.addTool(o2, new DOMPoint(100,100), 3);
let o2 = new GeomToolFromFile(p, "dd01", "/javascript/schoolkit/double_decimetre01.svg",
new DOMPoint(100,100), 1);
let o3 = new GeomToolFromFile(p, "equerre01", "/javascript/schoolkit/equerre01.svg",
new DOMPoint(300,150), 1);
