It looks like dino already tried to fix a few of these things. Can you please update your patch to account for those conflicts? Otherwise I think this looks good!

This is now conflicting with r215499.

This was landed in r215500.

I think this looks good, but I'm worried this might break GTK. Can you confirm?

Otherwise r=me.

Where did this go? Shouldn't it move to PlatformGTK or somewhere, like you did for Mac and Windows?

> Source/WebCore/platform/graphics/PlatformDisplay.cpp:-192
> -#endif

Oh, nice!

GTK port uses system ANGLE. So, no PlatformGTK.cmake. And, GTK EWS is green.

GTK port uses WebCore/CMakeLists.txt.  We need to remove this duplication, but they use ANGLE/libEGL/libGLESv2 differently than we do.  This is part of why we need to use the ANGLE renderer on Mac

wincairo-1 BuildBot cann't compile the new ANGLE, while wincairo-2 can.
I'm guessing VisualStudio 2015 Update 5 is needed for it.

As long as I'm updating, I updated my bot to Visual Studio 2017.  Works fine.
