From bbb62a69dd2b49d7cc4214937077c22b6997ffac Mon Sep 17 00:00:00 2001

Subject: [PATCH 4/5] ANGLE: Dynamically load D3D compiler from a list
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.
