Ruben Gonzalez 0b922b0e89 examples: zoom effect with compositor and navigations events
Use can change the video player zoom using the next keys:

  * +: Zoom in
  * -: Zoom out
  * Up/Down/Right/Left: Move the frame
  * r: reset the zoom

Also mouse navigation events can be used for a better UX.

Furthermore, it works with an pipeline using other video compositor
filters like glvideomixer. For instance:

  glvideomixer \
    name=mix background=1 \
    sink_0::xpos=0 sink_0::ypos=0 sink_0::zorder=0 \
    sink_0::width={WIDTH} sink_0::height={HEIGHT} \
  ! glimagesinkelement \
  gltestsrc pattern=mandelbrot name=src \
  ! video/x-raw(memory:GLMemory),framerate=30/1,width={WIDTH},height={HEIGHT},pixel-aspect-ratio=1/1 \
  ! queue \
  ! mix.sink_0

Probe was added in the sink pad to get direct navigation events w/o
transformation done by the mixer. More info about it in the PR [1].
