0004 Subject: [PATCH 02/17] ANGLE: Add support for querying platform device
0005
0006 The EGL_EXT_device_base extension allows for querying the platform
0007 device of the graphics hardware via eglQueryDisplayAttribEXT().
0008 As that extension is not supported by ANGLE, this patch adds similar
0009 functionality to the existing eglQuerySurfacePointerANGLE API. When
0010 EGL_DEVICE_EXT is passed as the queried attribute, the underlying
0011 D3D/DXGI device pointer is passed back to the caller via the value
0012 argument.
0013
0014 The D3D device is needed for the IDXGIDevice3::Trim() calls required by the Windows Store.
