Video as a sequence of OpenGL textures that can be easily played.

<p>
Constructor that initializes video from <a class="normal" href="CastleVideos.TVideo.html">TVideo</a> class.
<p><a class="normal" href="CastleVideos.TVideo.html">TVideo</a> passed here must be already <a class="normal" href="CastleVideos.TVideo.html#Loaded">Loaded</a>.
<p>Note that this class doesn't descend or keep reference to <a class="normal" href="CastleVideos.TVideo.html">TVideo</a> instance. The idea is that after creating <a class="normal" href="CastleGLImages.TGLVideo.html">TGLVideo</a> instance, you can often free original <a class="normal" href="CastleVideos.TVideo.html">TVideo</a> instance (if you care only about playing the movie). This can conserve memory greatly, as <a class="normal" href="CastleVideos.TVideo.html">TVideo</a> keeps all frames in the memory, and so is rather memory-costly. (Actually, <a class="normal" href="CastleGLImages.TGLVideo.html">TGLVideo</a> itself may eat a lot of texture memory, so be careful with large videos anyway.)</p>
