gst_video_overlay_set_window_handle() example for raspberry pi (or appsink)?

[munez bn]

The Native scaling function using set_render_rectangle didnt work for me.
It was not playing smoothly for some reason. So this is what I did

1] Create a dismpanx window based on video resolution. ( This part may be
missing in example code. I had hard-coded to  my test video resolution)
2] Set this window using set_window_hanlde ( refer to example code in the
bug)
3] Once this happens you have complete control over the window, you can
scale it, move it using dispmanx API
 vc_dispmanx_element_change_attributes()

The attached example is not optimized but enough for you to understand how
to scale and move(change dest rect  x, y value)..

Thanks & Regards
Munez
