pango: Create a new base class for all the elements This prevents the ugly hack where the text_sink pad template was only added for textoverlay but not for the subclasses. Also makes this work with the core change that made subclasses inherit the templates of their parent class.

/**
* SECTION:element-textoverlay
* @see_also: #GstTextRender, #GstClockOverlay, #GstTimeOverlay, #GstSubParse
*
* This plugin renders text on top of a video stream. This can be either
* static text or text from buffers received on the text sink pad, e.g.
* as produced by the subparse element. If the text sink pad is not linked,
* the text set via the "text" property will be rendered. If the text sink
* pad is linked, text will be rendered as it is received on that pad,
* honouring and matching the buffer timestamps of both input streams.
*
* The text can contain newline characters and text wrapping is enabled by
* default.
*
* <refsect2>
* <title>Example launch lines</title>
* |[
* gst-launch -v videotestsrc ! textoverlay text="Room A" valign=top halign=left ! xvimagesink
* ]| Here is a simple pipeline that displays a static text in the top left
* corner of the video picture
* |[
* gst-launch -v filesrc location=subtitles.srt ! subparse ! txt. videotestsrc ! timeoverlay ! textoverlay name=txt shaded-background=yes ! xvimagesink
* ]| Here is another pipeline that displays subtitles from an .srt subtitle
* file, centered at the bottom of the picture and with a rectangular shading
* around the text in the background:
* <para>
* If you do not have such a subtitle file, create one looking like this
* in a text editor:

* Hello? (3-5s)
*
* 2
* 00:00:08,000 --> 00:00:13,000
* Yes, this is a subtitle. Don&apos;t
* you like it? (8-13s)

* 00:00:18,826 --> 00:01:02,886

video: More video helper library improvements Make a new GstVideoFormatinfo structure that contains the specific information related to a format such as the number of planes, components, subsampling, pixel stride etc. The result is that we are now able to introduce the concept of components again in the API. Use tables to specify the formats and its properties. Use macros to get information about the video format description. Move code to set strides, offsets and size into one function. Remove methods that are not handled with the structures. Add methods to retrieve pointers and strides to the components in the video.
