* <refsect2>
* <para>
* This element resizes video frames. By default the element will try to
* negotiate to the same size on the source and sinkpad so that no scaling
* is needed. It is therefore safe to insert this element in a pipeline to
* get more robust behaviour without any cost if no scaling is needed.
* </para>
* <para>
* This element supports a wide range of color spaces including various YUV and
* RGB formats and is therefore generally able to operate anywhere in a
* pipeline.

* <para>
* <programlisting>
* gst-launch -v filesrc location=videotestsrc.ogg ! oggdemux ! theoradec ! videoconvert ! videoscale ! ximagesink
* </programlisting>
* Decode an Ogg/Theora and display the video using ximagesink. Since
* ximagesink cannot perform scaling, the video scaling will be performed by
* videoscale when you resize the video window.
* To create the test Ogg/Theora file refer to the documentation of theoraenc.
