* XImageSink renders video frames to a drawable (XWindow) on a local or remote
* display. This element can receive a Window ID from the application through
* the #GstVideoOverlay interface and will then render video frames in this
* drawable. If no Window ID was provided by the application, the element will
* create its own internal window and render into it.

* ## Scaling
*
* As standard XImage rendering to a drawable is not scaled, XImageSink will use
* reverse caps negotiation to try to get scaled video frames for the drawable.
* This is accomplished by asking the peer pad if it accepts some different caps
* which in most cases implies that there is a scaling element in the pipeline,
* or that an element generating the video frames can generate them with a
* different geometry. This mechanism is handled during buffer allocations, for
* each allocation request the video sink will check the drawable geometry, look

* desired video frames and then check that the peer pad accept those new caps.
* If it does it will then allocate a buffer in video memory with this new
* geometry and return it with the new caps.
*
* ## Events
*
* XImageSink creates a thread to handle events coming from the drawable. There
* are several kind of events that can be grouped in 2 big categories: input
* events and window state related events. Input events will be translated to
* navigation events and pushed upstream for other elements to react on them.
* This includes events such as pointer moves, key press/release, clicks etc...
* Other events are used to handle the drawable appearance even when the data
* is not flowing (GST_STATE_PAUSED). That means that even when the element is
* paused, it will receive expose events from the drawable and draw the latest
* frame with correct borders/aspect-ratio.

* This is faking a 4/3 pixel aspect ratio caps on video frames produced by
* videotestsrc, in most cases the pixel aspect ratio of the display will be
* 1/1. This means that videoscale will have to do the scaling to convert
* incoming frames to a size that will match the display pixel aspect ratio
* (from 320x240 to 320x180 in this case). Note that you might have to escape
* some characters for your shell like '\(fraction\)'.
