It seems quite important to have testing on Windows. Is there another way we
could test the Windows path? How long until the software compositor would be
available?

I have no idea. On the windows trybot, Graphics3D can not be created
sucessfully.

Ah yes I see that the Graphics3D tests are disabled on Windows Aura. piman@ do
you have any idea when this would be fixed. There is no bug linked in
ppapi_browsertest.cc.

Peng: Could we test everything except the cases that use Graphics3D?

[piman, 2014/06/19 01:21:21]

Not sure. If it's disabled on Windows but not Linux, this typically smells like
timeout-related flakiness.
Someone would need to sit down and investigate.

[Peng, 2014/06/19 20:04:48]

We can do it. But it need create a special test which doesn't use Graphics3D for
Windows Aura only. It is ugly. And Graphics3D does not work, probably because
GPU does not work too. I think the compositor should use GPU. So it may have
problem too.

So how about leave it as a TODO and enable it when Graphics3D works?
