Lots and lots of these kind of changes. This could be avoided by keeping the
base class named "WebGLRenderingContext" and naming the other class
"WebGL1RenderingContext" (It looks like Firefoxes current commits are doing
this) but since we don't want to change the name of the Javascript type (I
assume?) this would create a disconnect between the Javascript and C++ class
names/hierarchy. Personally I'd rather go through the pain of a large rename
once and preserve consistency moving forward.
