From 037550af14ce0ecebad96d637d7185b60d760b5d Mon Sep 17 00:00:00 2001

Subject: [PATCH 3/7] ANGLE: Add support for querying platform device
The EGL_EXT_device_base extension allows for querying the platform
device of the graphics hardware via eglQueryDisplayAttribEXT().
As that extension is not supported by ANGLE, this patch adds similar
functionality to the existing eglQuerySurfacePointerANGLE API. When
EGL_DEVICE_EXT is passed as the queried attribute, the underlying
D3D/DXGI device pointer is passed back to the caller via the value
argument.
The D3D device is needed for video support in QtMultimedia as well as
the IDXGIDevice3::Trim() calls required by the Windows Store.
