Load and unload 3D texture.

<p>When loading, we will try to set <a class="normal" href="X3DNodes.TAbstractTexture3DNode.html#TextureImage">TextureImage</a> and <a class="normal" href="X3DNodes.TAbstractTexture3DNode.html#TextureDDS">TextureDDS</a>. If loading is successfull, <a class="normal" href="X3DNodes.TAbstractTexture3DNode.html#TextureImage">TextureImage</a> will be always set to non-nil (<a class="normal" href="X3DNodes.TAbstractTexture3DNode.html#TextureDDS">TextureDDS</a> will be set to non-nil only if image came from some DDS image). If loading failed, both <a class="normal" href="X3DNodes.TAbstractTexture3DNode.html#TextureImage">TextureImage</a> and <a class="normal" href="X3DNodes.TAbstractTexture3DNode.html#TextureDDS">TextureDDS</a> will be <code>Nil</code>.

<p>Note that even when loading failed (<a class="normal" href="X3DNodes.TAbstractTexture3DNode.html#TextureImage">TextureImage</a> remained <code>Nil</code>), <code>TextureLoaded</code> value still changes to <code>True</code>. This is good &mdash; it makes assignment <code><code>TextureLoaded</code> := true</code> always work, and (more important) it prevents trying to load (and displaying uselessly the same <a class="normal" href="CastleWarnings.html#OnWarning">OnWarning</a>) again at successful <code><code>TextureLoaded</code> := true</code>.

<p>In case of problems (for example when some URL cannot be loaded), we will make <a class="normal" href="CastleWarnings.html#OnWarning">OnWarning</a>.</p>
