Seungha Yang fce7431381 d3d11: Install library headers
Our Direct3D11 abstraction layer has been improved and
it gained good shape from API point of view.
Also, On Windows, GstD3D11 has various advantages over GstGL
in terms of compatibility/stability/feature/performance.
Note that WGL implementation is known to be buggy for some
drivers/vendors/scenario (that's a reason why Google implemented ANGLE).
Moreover, GstGL is not fully optimized for Windows unfortunately.

It's the time to open this interface to application developers
for various optimized processing using our Direct3D11
infrastructure.

# FIXME: Probably DXGIGetDebugInterface1 might be used on UWP app for development
# purpose. So, I suspect one possible reason why WACK is complaining about
# DXGIGetDebugInterface1 is that debugging APIs couldn't be used for
# Windows store app, but couldn't find any reference about that.

# [IDXGIDebug1]
# https://docs.microsoft.com/en-us/windows/win32/api/dxgidebug/nn-dxgidebug-idxgidebug1
# is saying that the IDXGIDebug1 interface is available for both desktop app and
# UWP. And then the *DXGIGetDebugInterface1* method need to be called to obtain
# the IDXGIDebug1 interface.
#
# [DXGIGetDebugInterface1]
# https://docs.microsoft.com/en-us/windows/win32/api/dxgi1_3/nf-dxgi1_3-dxgigetdebuginterface1
# is mentioning that DXGIGetDebugInterface1 is desktop app only.

# PLEASE LET US KNOW A CORRECT WAY TO OBTAIN IDXGIDebug1 ON UWP, MICROSOFT
