This CL just marks those contexts to aid in debugging.

Do you have to pop these markers ever?

This would be better in LayerRendererChromium::initialize() - all WGC3D stuff should be down there.

No (or yes). They basically are just for debugging so when the gpu process prints a message it will print the marker. pushGroupMarker is like namespace. insertEventMarker sets the current "marker" for the current group. So

pushGroupMaker("foo");
enable(1234); // invalid enum
insertEventMarker("orange");
pushGroupMaker("bar");
enable(1234); // invalid enum
insertEventMarker("hello");
enable(1234); // invalid enum
insertEventMarker("world");
enable(1234); // invalid enum
popGroupMarker();
enable(1234); // invalid enum

should print something like

.foo: glEnable INVALID_ENUM
.foo.orange: glEnable INVALID_ENUM
.foo.bar: glEnable INVALID_ENUM
.foo.bar.hello: glEnable INVALID_ENUM
.foo.bar.word: glEnable INVALID_ENUM
.foo.orange: glEnable INVALID_ENUM

It's safe to pop too many times.

These values can get passed down to the driver and used in perf tools but I'm not currently passing them down to the driver
