Awesome work making these changes so thoroughly. I double-checked them and they
look perfect. LGTM

third_party/WebKit/Source/modules/webgl/WebGL2RenderingContextBase.cpp:2978:
DCHECK(query);
It's pretty cool and interesting that because the DCHECK was added to
validateWebGLObject that the object is non-null, that very few changes had to be
made to WebGLRenderingContextBase and WebGL2RenderingContextBase to assert the
arguments were non-null.
