This is to avoid a hang in glFinish in the event that the GPU hangs while the screen is locked.

To repro, modify this sample so that it waits a few seconds before hanging the GPU.

https://www.khronos.org/registry/webgl/conformance-suites/1.0.0/extra/lots-of-polys-example.html

After initiating the GPU hang, quickly lock the screen. The GPU will reset but ANGLE only ever sees S_PRESENT_OCCLUDED followed by D3DERR_NOERROR. It never sees the device lost error.

Calling Present while the screen is locked seems to make CheckDeviceState return the device lost.

Doing the extra Present in testDeviceLost every time did not work well because it is very slow, perhaps because D3D delays presents to hidden windows to throttle the app.

After calling Reset in testDeviceLost to acknowledge a display mode change, D3D sometimes crashes on the next Present call on an existing swap chain. I couldn't get it to happen with nVidia. The stack looks like this with the debug runtime:

 	ntdll.dll!_ZwRaiseException@12()  + 0x12 bytes

 	content.dll!content::PassThroughImageTransportSurface::SwapBuffers()  Line 216 + 0xb bytes	C++

The error is "BitBlt or StretchBlt failed in Present".

With the release runtime either Present continually fails with E_INVALIDARG or, less commonly, crashes.

It seems that by recreating all the swap chains after reset, it recovers. I didn't call resetSwapChain because there is no need to recreate all the other surfaces.

As far as I know, this should not be necessary with WDDM.

When CheckDeviceStats returns S_PRESENT_MODE_CHANGED, reset display mode and retest for device lost.

Unless the display mode is reset, CheckDeviceLost can keep returning S_PRESENT_MODE_CHANGED, potentially masking a device lost on account of a GPU hang, causing ANGLE to fail to report context lost.

Sometimes IDirect3DDevice9Ex::CheckDeviceState returns S_PRESENT_MODE_CHANGED when the GPU has hung. It's not consistent, maybe one time out of two when I hang the GPU while running WebGL Aquarium.

This unfortunately means that changes to display mode will cause ANGLE to report context lost. Other ideas appreciated.

This is an incompatible API change, but one which is necessary in
order to improve correctness of the code. The API version in
ShaderLang.h is updated and, unfortunately, the define renamed to
something less ambiguous due to conflicts on some Android buildbots.
Temporary patches in Chromium and WebKit will be landed separately to
support this upgrade.
