Inline node.
<p>The loaded inline contents are accessible in the <a class="normal" href="X3DNodes.TInlineNode.html#Inlined">Inlined</a> object. Currently this is also kept in the Children list of this node. Originally, Children list is for VRML 1.0 children, but for inline node this is just used for inlined content (regardless of VRML/X3D version).
<p>This means that most methods, like <a class="normal" href="X3DNodes.TX3DNode.html#EnumerateNodes">TX3DNode.EnumerateNodes</a>, descend into inlined content normally.</p>

Load inlined content <b>now</b>. If <a class="normal" href="X3DNodes.TInlineNode.html#Inlined">Inlined</a> is already loaded: if CanReload = <code>True</code> then it will be freed and loaded again, else (if CanReload = <code>False</code>) nothing will happen.
<p>Note that this has a really simple support for "load" field (this concerns VRML 97 amendment 1 "InlineLoadControl.load" and X3D (actually used also in VRML 97 handling) "Inline.load" fields). It simply doesn't do any loading when "load" = <code>False</code>.
<p>Note that this doesn't perform setting the "load" field, or sending any notifications to Scene about "load" field. It's the caller's job to keep loaded state synchronized with "load" field value.
<p><code>LoadInlined</code>(false) will be called automatically, to ensure the inlined contents are always loaded. It will be called at the end of Parse (this is needed to handle VRML/X3D IMPORT/EXPORT mechanism), it will also be called in <a class="normal" href="X3DNodes.TInlineNode.html#BeforeTraverse">BeforeTraverse</a> (in case you constructed node by code, not by parsing; this also happens when node was made by expanding a PROTO).
