Similar to cairooverlay element but this element emits "draw"
signal with Direct3D11 render target view, so that an application
can render/overlay/blend on the given render target view
without any copy operation

Add an example to show the usage of present singal.
In this example, a text overlay with alpha blended background
will be rendered on swapchain's backbuffer by using
Direct3D11, Direct2D, and DirectWrite APIs.

This example code demonstrates D3D11 device sharing between
application and GStreamer. Application can access texture
using appsink and it can be rendered on application's window without
any copy operation.
