VRML/X3D texture that is 2D and is loaded (from file or some other stream).
<p>For X3D, this descends from X3DTextureNode and is an ancestor for X3DTexture2DNode, so X3D hierarchy is nicely preserved.</p>

<p>
Duration for this time-dependent node. Duration is initialized from loaded video length (default is -1). So it's automatically initialized when you call <a class="normal" href="X3DNodes.TAbstractTexture2DNode.html#IsTextureVideo">IsTextureVideo</a>, <a class="normal" href="X3DNodes.TAbstractTexture2DNode.html#TextureVideo">TextureVideo</a> methods.
<p>cycleInterval is just set to duration scaled by 1/Abs(speed), like required by X3D spec.
<p>Duration (and so, also cycleInterval) is not reset when video is freed (like when you set <a class="normal" href="X3DNodes.TAbstractTexture2DNode.html#IsTextureLoaded">IsTextureLoaded</a> to <code>False</code>, maybe implicitly by calling <a class="normal" href="CastleSceneCore.TCastleSceneCore.html#FreeResources">TCastleSceneCore.FreeResources</a> with frTextureDataInNodes). This way this is available even you freed the texture video data to save memory.</p>
