From 0fede57f6fc052942b910995fdfa4cd76a32f586 Mon Sep 17 00:00:00 2001

Subject: [PATCH] ANGLE: Dynamically load D3D compiler from a list or the
environment
If the default compiler cannot be found, load it from a list of DLL names,
including a non-versioned proxy DLL provided by Qt. On Desktop Windows,
the default compiler can also be specified by an environment variable,
QT_D3DCOMPILER_DLL.
