Subject: [PATCH] Modified CreateShaderResourceView() calls to use descriptiors
 from prior SRVs to handle cases where SRV format cannot be directly deduced
 from texture format. This happens when using D3D11's typeless texture
 formats, which can be introduced into a BGFX app using overrideInternal.
