e8666a7f94 examples: d3d11videosink: Add present signal example
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.

66d504ee58 d3d11: Don't find global default allocator
We were using global default allocator already. Pass null
allocator object to *_alloc() methods then the method will
use default allocator.

347ad181be d3d11memory: Update alloc_wrapped() API to avoid staging texture alloc
Add size parameter and use it for CPU accessible memory size
instead of allocating staging texture per API call.

260114fa1b examples: Add an example for application texture sharing
This example shows GstD3D11BufferPool usage and a way of
D3D11 texture sharing between application and GStreamer via appsrc.

dbed379f09 examples: Add d3d11decoder zero-copy rendering example
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.

e0a9a73adf d3d11screencapturesrc: Fix crash when d3d11 device is different from owned one
GstD3D11ScreenCapture object is pipeline-independent global object
and the object can be shared by multiple src elements,
in order to overcome a limitation of DXGI Desktop Duplication API.
Note that the API allows only single capture session in a process for
a monitor.

Therefore GstD3D11ScreenCapture object must be able to handle a case
where a src element holds different GstD3D11Device object. Which can
happen when GstD3D11Device context is not shared by pipelines.

What's changed:
* Allocates capture texture with D3D11_RESOURCE_MISC_SHARED for the
  texture to be able to copied into other device's texture
* Holds additional shader objects per src element and use it when drawing
  mouse
