<p>
A plugin in grits is a GObject which implements the GritsPlugin interface.
Additionally, each plugin is compiled to a separate shared object and loaded
conditionally at runtime when the plugin is enabled. Each such shared object
should define a <a class="link" href="grits-GritsPlugin.html#GritsPluginConstructor" title="GritsPluginConstructor ()"><code class="function">GritsPluginConstructor()</code></a> function named
grits_plugin_NAME_new which will be called when loading the plugin.
</p>
<p>
Almost all grits functionality is provided by a set of plugins. Each plugin
can how however much it likes. The interface between plugins and the rest of
grits is intentionally very thin. Since grits is the library, plugins must
manually do everything. For instance, to draw something in the world, the
plugin must add an object to the viewer. Likewise, plugins need to
register callbacks on the viewer in order to receive updates, very little
happens automagically.
</p>
<p>
That being said, one thing that plugins do do automagically, is provide a
configuration area. Since the plugin doesn't know what application is is
being loaded form, it is better for the application to ask the plugin for
it's confirmation area, not the other way around.
